Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537844, here are decompositions:

7 + 31537837 = 31537844
97 + 31537747 = 31537844
103 + 31537741 = 31537844
127 + 31537717 = 31537844
157 + 31537687 = 31537844
241 + 31537603 = 31537844
271 + 31537573 = 31537844
337 + 31537507 = 31537844

Showing the first eight; more decompositions exist.
