Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603562, here are decompositions:

43 + 31603519 = 31603562
73 + 31603489 = 31603562
181 + 31603381 = 31603562
313 + 31603249 = 31603562
421 + 31603141 = 31603562
439 + 31603123 = 31603562
631 + 31602931 = 31603562
709 + 31602853 = 31603562

Showing the first eight; more decompositions exist.
