Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511706, here are decompositions:

29 + 31511677 = 31511706
53 + 31511653 = 31511706
137 + 31511569 = 31511706
157 + 31511549 = 31511706
167 + 31511539 = 31511706
173 + 31511533 = 31511706
179 + 31511527 = 31511706
223 + 31511483 = 31511706

Showing the first eight; more decompositions exist.
