Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624508, here are decompositions:

31 + 31624477 = 31624508
79 + 31624429 = 31624508
151 + 31624357 = 31624508
367 + 31624141 = 31624508
379 + 31624129 = 31624508
439 + 31624069 = 31624508
541 + 31623967 = 31624508
577 + 31623931 = 31624508

Showing the first eight; more decompositions exist.
