Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601624, here are decompositions:

73 + 31601551 = 31601624
97 + 31601527 = 31601624
151 + 31601473 = 31601624
277 + 31601347 = 31601624
283 + 31601341 = 31601624
421 + 31601203 = 31601624
433 + 31601191 = 31601624
487 + 31601137 = 31601624

Showing the first eight; more decompositions exist.
