Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454758, here are decompositions:

17 + 31454741 = 31454758
89 + 31454669 = 31454758
107 + 31454651 = 31454758
131 + 31454627 = 31454758
317 + 31454441 = 31454758
509 + 31454249 = 31454758
557 + 31454201 = 31454758
641 + 31454117 = 31454758

Showing the first eight; more decompositions exist.
