Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464836, here are decompositions:

79 + 31464757 = 31464836
127 + 31464709 = 31464836
373 + 31464463 = 31464836
397 + 31464439 = 31464836
409 + 31464427 = 31464836
439 + 31464397 = 31464836
643 + 31464193 = 31464836
757 + 31464079 = 31464836

Showing the first eight; more decompositions exist.
