Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473076, here are decompositions:

113 + 31472963 = 31473076
149 + 31472927 = 31473076
197 + 31472879 = 31473076
227 + 31472849 = 31473076
263 + 31472813 = 31473076
269 + 31472807 = 31473076
353 + 31472723 = 31473076
443 + 31472633 = 31473076

Showing the first eight; more decompositions exist.
