Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624412, here are decompositions:

73 + 31624339 = 31624412
271 + 31624141 = 31624412
283 + 31624129 = 31624412
409 + 31624003 = 31624412
433 + 31623979 = 31624412
691 + 31623721 = 31624412
709 + 31623703 = 31624412
823 + 31623589 = 31624412

Showing the first eight; more decompositions exist.
