Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508710, here are decompositions:

29 + 31508681 = 31508710
53 + 31508657 = 31508710
59 + 31508651 = 31508710
71 + 31508639 = 31508710
89 + 31508621 = 31508710
131 + 31508579 = 31508710
257 + 31508453 = 31508710
293 + 31508417 = 31508710

Showing the first eight; more decompositions exist.
