Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472386, here are decompositions:

47 + 31472339 = 31472386
227 + 31472159 = 31472386
233 + 31472153 = 31472386
263 + 31472123 = 31472386
317 + 31472069 = 31472386
383 + 31472003 = 31472386
419 + 31471967 = 31472386
479 + 31471907 = 31472386

Showing the first eight; more decompositions exist.
