Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603964, here are decompositions:

31 + 31603933 = 31603964
163 + 31603801 = 31603964
283 + 31603681 = 31603964
307 + 31603657 = 31603964
397 + 31603567 = 31603964
571 + 31603393 = 31603964
823 + 31603141 = 31603964
853 + 31603111 = 31603964

Showing the first eight; more decompositions exist.
