Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510004, here are decompositions:

3 + 31510001 = 31510004
13 + 31509991 = 31510004
37 + 31509967 = 31510004
223 + 31509781 = 31510004
241 + 31509763 = 31510004
307 + 31509697 = 31510004
313 + 31509691 = 31510004
433 + 31509571 = 31510004

Showing the first eight; more decompositions exist.
