Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624202, here are decompositions:

61 + 31624141 = 31624202
73 + 31624129 = 31624202
199 + 31624003 = 31624202
223 + 31623979 = 31624202
271 + 31623931 = 31624202
499 + 31623703 = 31624202
613 + 31623589 = 31624202
691 + 31623511 = 31624202

Showing the first eight; more decompositions exist.
