Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456454, here are decompositions:

13 + 31456441 = 31456454
163 + 31456291 = 31456454
331 + 31456123 = 31456454
433 + 31456021 = 31456454
577 + 31455877 = 31456454
613 + 31455841 = 31456454
727 + 31455727 = 31456454
751 + 31455703 = 31456454

Showing the first eight; more decompositions exist.
