Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624454, here are decompositions:

31 + 31624423 = 31624454
67 + 31624387 = 31624454
97 + 31624357 = 31624454
307 + 31624147 = 31624454
313 + 31624141 = 31624454
487 + 31623967 = 31624454
523 + 31623931 = 31624454
733 + 31623721 = 31624454

Showing the first eight; more decompositions exist.
