Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495904, here are decompositions:

7 + 31495897 = 31495904
103 + 31495801 = 31495904
151 + 31495753 = 31495904
163 + 31495741 = 31495904
211 + 31495693 = 31495904
241 + 31495663 = 31495904
313 + 31495591 = 31495904
457 + 31495447 = 31495904

Showing the first eight; more decompositions exist.
