Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603238, here are decompositions:

97 + 31603141 = 31603238
127 + 31603111 = 31603238
211 + 31603027 = 31603238
229 + 31603009 = 31603238
307 + 31602931 = 31603238
379 + 31602859 = 31603238
547 + 31602691 = 31603238
577 + 31602661 = 31603238

Showing the first eight; more decompositions exist.
