Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623584, here are decompositions:

61 + 31623523 = 31623584
73 + 31623511 = 31623584
103 + 31623481 = 31623584
163 + 31623421 = 31623584
211 + 31623373 = 31623584
241 + 31623343 = 31623584
373 + 31623211 = 31623584
463 + 31623121 = 31623584

Showing the first eight; more decompositions exist.
