Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508954, here are decompositions:

7 + 31508947 = 31508954
67 + 31508887 = 31508954
97 + 31508857 = 31508954
163 + 31508791 = 31508954
223 + 31508731 = 31508954
241 + 31508713 = 31508954
271 + 31508683 = 31508954
277 + 31508677 = 31508954

Showing the first eight; more decompositions exist.
