Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603448, here are decompositions:

67 + 31603381 = 31603448
139 + 31603309 = 31603448
199 + 31603249 = 31603448
307 + 31603141 = 31603448
337 + 31603111 = 31603448
421 + 31603027 = 31603448
439 + 31603009 = 31603448
571 + 31602877 = 31603448

Showing the first eight; more decompositions exist.
