Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454998, here are decompositions:

41 + 31454957 = 31454998
89 + 31454909 = 31454998
131 + 31454867 = 31454998
257 + 31454741 = 31454998
317 + 31454681 = 31454998
347 + 31454651 = 31454998
557 + 31454441 = 31454998
647 + 31454351 = 31454998

Showing the first eight; more decompositions exist.
