Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608586, here are decompositions:

59 + 31608527 = 31608586
89 + 31608497 = 31608586
137 + 31608449 = 31608586
419 + 31608167 = 31608586
479 + 31608107 = 31608586
557 + 31608029 = 31608586
617 + 31607969 = 31608586
677 + 31607909 = 31608586

Showing the first eight; more decompositions exist.
