Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464844, here are decompositions:

17 + 31464827 = 31464844
23 + 31464821 = 31464844
113 + 31464731 = 31464844
227 + 31464617 = 31464844
263 + 31464581 = 31464844
401 + 31464443 = 31464844
443 + 31464401 = 31464844
503 + 31464341 = 31464844

Showing the first eight; more decompositions exist.
