Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462328, here are decompositions:

61 + 31462267 = 31462328
307 + 31462021 = 31462328
349 + 31461979 = 31462328
367 + 31461961 = 31462328
379 + 31461949 = 31462328
409 + 31461919 = 31462328
487 + 31461841 = 31462328
631 + 31461697 = 31462328

Showing the first eight; more decompositions exist.
