Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508834, here are decompositions:

43 + 31508791 = 31508834
103 + 31508731 = 31508834
151 + 31508683 = 31508834
157 + 31508677 = 31508834
163 + 31508671 = 31508834
277 + 31508557 = 31508834
307 + 31508527 = 31508834
373 + 31508461 = 31508834

Showing the first eight; more decompositions exist.
