Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461272, here are decompositions:

19 + 31461253 = 31461272
43 + 31461229 = 31461272
79 + 31461193 = 31461272
109 + 31461163 = 31461272
223 + 31461049 = 31461272
421 + 31460851 = 31461272
433 + 31460839 = 31461272
439 + 31460833 = 31461272

Showing the first eight; more decompositions exist.
