Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471746, here are decompositions:

43 + 31471703 = 31471746
79 + 31471667 = 31471746
83 + 31471663 = 31471746
107 + 31471639 = 31471746
109 + 31471637 = 31471746
113 + 31471633 = 31471746
167 + 31471579 = 31471746
197 + 31471549 = 31471746

Showing the first eight; more decompositions exist.
