Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472776, here are decompositions:

3 + 31472773 = 31472776
53 + 31472723 = 31472776
107 + 31472669 = 31472776
113 + 31472663 = 31472776
239 + 31472537 = 31472776
593 + 31472183 = 31472776
617 + 31472159 = 31472776
653 + 31472123 = 31472776

Showing the first eight; more decompositions exist.
