Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456634, here are decompositions:

37 + 31456597 = 31456634
103 + 31456531 = 31456634
193 + 31456441 = 31456634
397 + 31456237 = 31456634
541 + 31456093 = 31456634
613 + 31456021 = 31456634
631 + 31456003 = 31456634
673 + 31455961 = 31456634

Showing the first eight; more decompositions exist.
