Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624556, here are decompositions:

79 + 31624477 = 31624556
127 + 31624429 = 31624556
193 + 31624363 = 31624556
199 + 31624357 = 31624556
409 + 31624147 = 31624556
487 + 31624069 = 31624556
577 + 31623979 = 31624556
739 + 31623817 = 31624556

Showing the first eight; more decompositions exist.
