Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603762, here are decompositions:

5 + 31603757 = 31603762
11 + 31603751 = 31603762
23 + 31603739 = 31603762
41 + 31603721 = 31603762
53 + 31603709 = 31603762
149 + 31603613 = 31603762
251 + 31603511 = 31603762
401 + 31603361 = 31603762

Showing the first eight; more decompositions exist.
