Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603310, here are decompositions:

61 + 31603249 = 31603310
163 + 31603147 = 31603310
199 + 31603111 = 31603310
283 + 31603027 = 31603310
337 + 31602973 = 31603310
379 + 31602931 = 31603310
433 + 31602877 = 31603310
457 + 31602853 = 31603310

Showing the first eight; more decompositions exist.
