Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1742, here are decompositions:
- 19 + 1723 = 1742
- 43 + 1699 = 1742
- 73 + 1669 = 1742
- 79 + 1663 = 1742
- 163 + 1579 = 1742
- 193 + 1549 = 1742
- 199 + 1543 = 1742
- 211 + 1531 = 1742
Showing the first eight; more decompositions exist.

The digit sequence 1742 first appears in π at position 20,466 of the decimal expansion (the 20,466ordinal-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.
