Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624304, here are decompositions:

157 + 31624147 = 31624304
163 + 31624141 = 31624304
337 + 31623967 = 31624304
373 + 31623931 = 31624304
487 + 31623817 = 31624304
601 + 31623703 = 31624304
823 + 31623481 = 31624304
883 + 31623421 = 31624304

Showing the first eight; more decompositions exist.
