Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624124, here are decompositions:

157 + 31623967 = 31624124
193 + 31623931 = 31624124
223 + 31623901 = 31624124
307 + 31623817 = 31624124
421 + 31623703 = 31624124
457 + 31623667 = 31624124
601 + 31623523 = 31624124
613 + 31623511 = 31624124

Showing the first eight; more decompositions exist.
