Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464268, here are decompositions:

131 + 31464137 = 31464268
347 + 31463921 = 31464268
359 + 31463909 = 31464268
389 + 31463879 = 31464268
419 + 31463849 = 31464268
461 + 31463807 = 31464268
509 + 31463759 = 31464268
587 + 31463681 = 31464268

Showing the first eight; more decompositions exist.
