Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624052, here are decompositions:

73 + 31623979 = 31624052
151 + 31623901 = 31624052
331 + 31623721 = 31624052
349 + 31623703 = 31624052
463 + 31623589 = 31624052
541 + 31623511 = 31624052
571 + 31623481 = 31624052
613 + 31623439 = 31624052

Showing the first eight; more decompositions exist.
