Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603752, here are decompositions:

13 + 31603739 = 31603752
31 + 31603721 = 31603752
41 + 31603711 = 31603752
43 + 31603709 = 31603752
71 + 31603681 = 31603752
109 + 31603643 = 31603752
139 + 31603613 = 31603752
199 + 31603553 = 31603752

Showing the first eight; more decompositions exist.
