Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547948, here are decompositions:

31 + 31547917 = 31547948
97 + 31547851 = 31547948
109 + 31547839 = 31547948
199 + 31547749 = 31547948
241 + 31547707 = 31547948
277 + 31547671 = 31547948
307 + 31547641 = 31547948
331 + 31547617 = 31547948

Showing the first eight; more decompositions exist.
