Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607042, here are decompositions:

3 + 31607039 = 31607042
79 + 31606963 = 31607042
139 + 31606903 = 31607042
163 + 31606879 = 31607042
331 + 31606711 = 31607042
463 + 31606579 = 31607042
499 + 31606543 = 31607042
613 + 31606429 = 31607042

Showing the first eight; more decompositions exist.
