Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456352, here are decompositions:

61 + 31456291 = 31456352
73 + 31456279 = 31456352
229 + 31456123 = 31456352
331 + 31456021 = 31456352
349 + 31456003 = 31456352
463 + 31455889 = 31456352
523 + 31455829 = 31456352
601 + 31455751 = 31456352

Showing the first eight; more decompositions exist.
