Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501844, here are decompositions:

13 + 31501831 = 31501844
37 + 31501807 = 31501844
103 + 31501741 = 31501844
211 + 31501633 = 31501844
223 + 31501621 = 31501844
277 + 31501567 = 31501844
307 + 31501537 = 31501844
313 + 31501531 = 31501844

Showing the first eight; more decompositions exist.
