Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472926, here are decompositions:

47 + 31472879 = 31472926
59 + 31472867 = 31472926
113 + 31472813 = 31472926
227 + 31472699 = 31472926
257 + 31472669 = 31472926
263 + 31472663 = 31472926
293 + 31472633 = 31472926
389 + 31472537 = 31472926

Showing the first eight; more decompositions exist.
