Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458034, here are decompositions:

131 + 31457903 = 31458034
173 + 31457861 = 31458034
191 + 31457843 = 31458034
263 + 31457771 = 31458034
281 + 31457753 = 31458034
317 + 31457717 = 31458034
347 + 31457687 = 31458034
353 + 31457681 = 31458034

Showing the first eight; more decompositions exist.
