Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510052, here are decompositions:

31 + 31510021 = 31510052
43 + 31510009 = 31510052
61 + 31509991 = 31510052
103 + 31509949 = 31510052
139 + 31509913 = 31510052
163 + 31509889 = 31510052
271 + 31509781 = 31510052
313 + 31509739 = 31510052

Showing the first eight; more decompositions exist.
