Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461256, here are decompositions:

3 + 31461253 = 31461256
83 + 31461173 = 31461256
107 + 31461149 = 31461256
383 + 31460873 = 31461256
419 + 31460837 = 31461256
599 + 31460657 = 31461256
647 + 31460609 = 31461256
719 + 31460537 = 31461256

Showing the first eight; more decompositions exist.
