Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537746, here are decompositions:

5 + 31537741 = 31537746
29 + 31537717 = 31537746
59 + 31537687 = 31537746
137 + 31537609 = 31537746
173 + 31537573 = 31537746
199 + 31537547 = 31537746
239 + 31537507 = 31537746
269 + 31537477 = 31537746

Showing the first eight; more decompositions exist.
