Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462256, here are decompositions:

277 + 31461979 = 31462256
307 + 31461949 = 31462256
313 + 31461943 = 31462256
337 + 31461919 = 31462256
433 + 31461823 = 31462256
439 + 31461817 = 31462256
733 + 31461523 = 31462256
739 + 31461517 = 31462256

Showing the first eight; more decompositions exist.
