Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603352, here are decompositions:

43 + 31603309 = 31603352
103 + 31603249 = 31603352
211 + 31603141 = 31603352
229 + 31603123 = 31603352
241 + 31603111 = 31603352
379 + 31602973 = 31603352
421 + 31602931 = 31603352
499 + 31602853 = 31603352

Showing the first eight; more decompositions exist.
