Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464982, here are decompositions:

41 + 31464941 = 31464982
173 + 31464809 = 31464982
251 + 31464731 = 31464982
281 + 31464701 = 31464982
401 + 31464581 = 31464982
641 + 31464341 = 31464982
701 + 31464281 = 31464982
839 + 31464143 = 31464982

Showing the first eight; more decompositions exist.
