Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457246, here are decompositions:

19 + 31457227 = 31457246
43 + 31457203 = 31457246
97 + 31457149 = 31457246
127 + 31457119 = 31457246
397 + 31456849 = 31457246
577 + 31456669 = 31457246
607 + 31456639 = 31457246
967 + 31456279 = 31457246

Showing the first eight; more decompositions exist.
