Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603756, here are decompositions:

5 + 31603751 = 31603756
17 + 31603739 = 31603756
47 + 31603709 = 31603756
113 + 31603643 = 31603756
179 + 31603577 = 31603756
269 + 31603487 = 31603756
389 + 31603367 = 31603756
563 + 31603193 = 31603756

Showing the first eight; more decompositions exist.
