Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537994, here are decompositions:

13 + 31537981 = 31537994
73 + 31537921 = 31537994
151 + 31537843 = 31537994
157 + 31537837 = 31537994
277 + 31537717 = 31537994
307 + 31537687 = 31537994
421 + 31537573 = 31537994
487 + 31537507 = 31537994

Showing the first eight; more decompositions exist.
