Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507702, here are decompositions:

3 + 31507699 = 31507702
41 + 31507661 = 31507702
131 + 31507571 = 31507702
179 + 31507523 = 31507702
383 + 31507319 = 31507702
419 + 31507283 = 31507702
431 + 31507271 = 31507702
491 + 31507211 = 31507702

Showing the first eight; more decompositions exist.
