Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624462, here are decompositions:

5 + 31624457 = 31624462
113 + 31624349 = 31624462
131 + 31624331 = 31624462
179 + 31624283 = 31624462
449 + 31624013 = 31624462
461 + 31624001 = 31624462
479 + 31623983 = 31624462
491 + 31623971 = 31624462

Showing the first eight; more decompositions exist.
