Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603792, here are decompositions:

41 + 31603751 = 31603792
53 + 31603739 = 31603792
71 + 31603721 = 31603792
83 + 31603709 = 31603792
149 + 31603643 = 31603792
179 + 31603613 = 31603792
239 + 31603553 = 31603792
281 + 31603511 = 31603792

Showing the first eight; more decompositions exist.
