Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1750, here are decompositions:

3 + 1747 = 1750
17 + 1733 = 1750
29 + 1721 = 1750
41 + 1709 = 1750
53 + 1697 = 1750
83 + 1667 = 1750
113 + 1637 = 1750
131 + 1619 = 1750

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1750 first appears in π at position 33,139 of the decimal expansion (the 33,139ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
