Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603796, here are decompositions:

79 + 31603717 = 31603796
139 + 31603657 = 31603796
229 + 31603567 = 31603796
277 + 31603519 = 31603796
307 + 31603489 = 31603796
487 + 31603309 = 31603796
547 + 31603249 = 31603796
673 + 31603123 = 31603796

Showing the first eight; more decompositions exist.
