Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472116, here are decompositions:

47 + 31472069 = 31472116
113 + 31472003 = 31472116
149 + 31471967 = 31472116
233 + 31471883 = 31472116
293 + 31471823 = 31472116
317 + 31471799 = 31472116
353 + 31471763 = 31472116
419 + 31471697 = 31472116

Showing the first eight; more decompositions exist.
