Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459318, here are decompositions:

29 + 31459289 = 31459318
101 + 31459217 = 31459318
167 + 31459151 = 31459318
521 + 31458797 = 31459318
557 + 31458761 = 31459318
599 + 31458719 = 31459318
617 + 31458701 = 31459318
881 + 31458437 = 31459318

Showing the first eight; more decompositions exist.
