Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2230, here are decompositions:

17 + 2213 = 2230
23 + 2207 = 2230
89 + 2141 = 2230
101 + 2129 = 2230
131 + 2099 = 2230
149 + 2081 = 2230
167 + 2063 = 2230
191 + 2039 = 2230

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2230 first appears in π at position 824 of the decimal expansion (the 824ordinal-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.
