Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494956, here are decompositions:

7 + 31494949 = 31494956
13 + 31494943 = 31494956
19 + 31494937 = 31494956
37 + 31494919 = 31494956
139 + 31494817 = 31494956
193 + 31494763 = 31494956
277 + 31494679 = 31494956
313 + 31494643 = 31494956

Showing the first eight; more decompositions exist.
