Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537946, here are decompositions:

7 + 31537939 = 31537946
43 + 31537903 = 31537946
103 + 31537843 = 31537946
109 + 31537837 = 31537946
199 + 31537747 = 31537946
229 + 31537717 = 31537946
337 + 31537609 = 31537946
373 + 31537573 = 31537946

Showing the first eight; more decompositions exist.
