Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454718, here are decompositions:

17 + 31454701 = 31454718
37 + 31454681 = 31454718
67 + 31454651 = 31454718
131 + 31454587 = 31454718
257 + 31454461 = 31454718
277 + 31454441 = 31454718
367 + 31454351 = 31454718
397 + 31454321 = 31454718

Showing the first eight; more decompositions exist.
