Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483718, here are decompositions:

271 + 31483447 = 31483718
349 + 31483369 = 31483718
367 + 31483351 = 31483718
457 + 31483261 = 31483718
601 + 31483117 = 31483718
631 + 31483087 = 31483718
727 + 31482991 = 31483718
811 + 31482907 = 31483718

Showing the first eight; more decompositions exist.
