Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458064, here are decompositions:

3 + 31458061 = 31458064
233 + 31457831 = 31458064
293 + 31457771 = 31458064
311 + 31457753 = 31458064
347 + 31457717 = 31458064
383 + 31457681 = 31458064
461 + 31457603 = 31458064
593 + 31457471 = 31458064

Showing the first eight; more decompositions exist.
