Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458766, here are decompositions:

5 + 31458761 = 31458766
47 + 31458719 = 31458766
173 + 31458593 = 31458766
179 + 31458587 = 31458766
239 + 31458527 = 31458766
347 + 31458419 = 31458766
389 + 31458377 = 31458766
467 + 31458299 = 31458766

Showing the first eight; more decompositions exist.
