Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603376, here are decompositions:

67 + 31603309 = 31603376
127 + 31603249 = 31603376
229 + 31603147 = 31603376
349 + 31603027 = 31603376
367 + 31603009 = 31603376
499 + 31602877 = 31603376
523 + 31602853 = 31603376
613 + 31602763 = 31603376

Showing the first eight; more decompositions exist.
