Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464838, here are decompositions:

11 + 31464827 = 31464838
17 + 31464821 = 31464838
29 + 31464809 = 31464838
107 + 31464731 = 31464838
137 + 31464701 = 31464838
257 + 31464581 = 31464838
281 + 31464557 = 31464838
479 + 31464359 = 31464838

Showing the first eight; more decompositions exist.
