Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500796, here are decompositions:

3 + 31500793 = 31500796
23 + 31500773 = 31500796
29 + 31500767 = 31500796
59 + 31500737 = 31500796
83 + 31500713 = 31500796
137 + 31500659 = 31500796
227 + 31500569 = 31500796
293 + 31500503 = 31500796

Showing the first eight; more decompositions exist.
