Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464868, here are decompositions:

41 + 31464827 = 31464868
47 + 31464821 = 31464868
59 + 31464809 = 31464868
137 + 31464731 = 31464868
167 + 31464701 = 31464868
251 + 31464617 = 31464868
311 + 31464557 = 31464868
359 + 31464509 = 31464868

Showing the first eight; more decompositions exist.
