Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603682, here are decompositions:

73 + 31603609 = 31603682
163 + 31603519 = 31603682
193 + 31603489 = 31603682
373 + 31603309 = 31603682
421 + 31603261 = 31603682
433 + 31603249 = 31603682
541 + 31603141 = 31603682
571 + 31603111 = 31603682

Showing the first eight; more decompositions exist.
