Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537850, here are decompositions:

7 + 31537843 = 31537850
13 + 31537837 = 31537850
103 + 31537747 = 31537850
109 + 31537741 = 31537850
163 + 31537687 = 31537850
241 + 31537609 = 31537850
277 + 31537573 = 31537850
307 + 31537543 = 31537850

Showing the first eight; more decompositions exist.
