Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603774, here are decompositions:

17 + 31603757 = 31603774
23 + 31603751 = 31603774
53 + 31603721 = 31603774
131 + 31603643 = 31603774
197 + 31603577 = 31603774
263 + 31603511 = 31603774
347 + 31603427 = 31603774
431 + 31603343 = 31603774

Showing the first eight; more decompositions exist.
