Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603262, here are decompositions:

3 + 31603259 = 31603262
13 + 31603249 = 31603262
139 + 31603123 = 31603262
151 + 31603111 = 31603262
331 + 31602931 = 31603262
409 + 31602853 = 31603262
499 + 31602763 = 31603262
571 + 31602691 = 31603262

Showing the first eight; more decompositions exist.
