Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508038, here are decompositions:

11 + 31508027 = 31508038
47 + 31507991 = 31508038
137 + 31507901 = 31508038
251 + 31507787 = 31508038
431 + 31507607 = 31508038
461 + 31507577 = 31508038
467 + 31507571 = 31508038
677 + 31507361 = 31508038

Showing the first eight; more decompositions exist.
