Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508826, here are decompositions:

79 + 31508747 = 31508826
113 + 31508713 = 31508826
149 + 31508677 = 31508826
179 + 31508647 = 31508826
257 + 31508569 = 31508826
269 + 31508557 = 31508826
277 + 31508549 = 31508826
317 + 31508509 = 31508826

Showing the first eight; more decompositions exist.
