Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542046, here are decompositions:

23 + 31542023 = 31542046
113 + 31541933 = 31542046
353 + 31541693 = 31542046
449 + 31541597 = 31542046
563 + 31541483 = 31542046
617 + 31541429 = 31542046
647 + 31541399 = 31542046
929 + 31541117 = 31542046

Showing the first eight; more decompositions exist.
