Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504968, here are decompositions:

17 + 31504951 = 31504968
59 + 31504909 = 31504968
149 + 31504819 = 31504968
167 + 31504801 = 31504968
277 + 31504691 = 31504968
307 + 31504661 = 31504968
317 + 31504651 = 31504968
349 + 31504619 = 31504968

Showing the first eight; more decompositions exist.
