Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530764, here are decompositions:

61 + 31530703 = 31530764
103 + 31530661 = 31530764
127 + 31530637 = 31530764
157 + 31530607 = 31530764
193 + 31530571 = 31530764
241 + 31530523 = 31530764
277 + 31530487 = 31530764
313 + 31530451 = 31530764

Showing the first eight; more decompositions exist.
