Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497976, here are decompositions:

47 + 31497929 = 31497976
113 + 31497863 = 31497976
149 + 31497827 = 31497976
173 + 31497803 = 31497976
179 + 31497797 = 31497976
239 + 31497737 = 31497976
269 + 31497707 = 31497976
449 + 31497527 = 31497976

Showing the first eight; more decompositions exist.
