Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544808, here are decompositions:

37 + 31544771 = 31544808
59 + 31544749 = 31544808
89 + 31544719 = 31544808
151 + 31544657 = 31544808
257 + 31544551 = 31544808
277 + 31544531 = 31544808
461 + 31544347 = 31544808
587 + 31544221 = 31544808

Showing the first eight; more decompositions exist.
