Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624076, here are decompositions:

7 + 31624069 = 31624076
73 + 31624003 = 31624076
97 + 31623979 = 31624076
109 + 31623967 = 31624076
373 + 31623703 = 31624076
409 + 31623667 = 31624076
487 + 31623589 = 31624076
577 + 31623499 = 31624076

Showing the first eight; more decompositions exist.
