Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472110, here are decompositions:

3 + 31472107 = 31472110
41 + 31472069 = 31472110
107 + 31472003 = 31472110
227 + 31471883 = 31472110
311 + 31471799 = 31472110
347 + 31471763 = 31472110
443 + 31471667 = 31472110
587 + 31471523 = 31472110

Showing the first eight; more decompositions exist.
