Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507632, here are decompositions:

41 + 31507591 = 31507632
59 + 31507573 = 31507632
61 + 31507571 = 31507632
71 + 31507561 = 31507632
109 + 31507523 = 31507632
173 + 31507459 = 31507632
229 + 31507403 = 31507632
269 + 31507363 = 31507632

Showing the first eight; more decompositions exist.
