Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456562, here are decompositions:

31 + 31456531 = 31456562
61 + 31456501 = 31456562
271 + 31456291 = 31456562
283 + 31456279 = 31456562
439 + 31456123 = 31456562
463 + 31456099 = 31456562
541 + 31456021 = 31456562
601 + 31455961 = 31456562

Showing the first eight; more decompositions exist.
