Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501094, here are decompositions:

3 + 31501091 = 31501094
13 + 31501081 = 31501094
127 + 31500967 = 31501094
223 + 31500871 = 31501094
241 + 31500853 = 31501094
277 + 31500817 = 31501094
607 + 31500487 = 31501094
631 + 31500463 = 31501094

Showing the first eight; more decompositions exist.
