Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499766, here are decompositions:

5 + 31499761 = 31499766
107 + 31499659 = 31499766
167 + 31499599 = 31499766
173 + 31499593 = 31499766
229 + 31499537 = 31499766
269 + 31499497 = 31499766
307 + 31499459 = 31499766
359 + 31499407 = 31499766

Showing the first eight; more decompositions exist.
