Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624070, here are decompositions:

67 + 31624003 = 31624070
103 + 31623967 = 31624070
139 + 31623931 = 31624070
349 + 31623721 = 31624070
367 + 31623703 = 31624070
463 + 31623607 = 31624070
547 + 31623523 = 31624070
571 + 31623499 = 31624070

Showing the first eight; more decompositions exist.
