Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450476, here are decompositions:

47 + 31450429 = 31450476
53 + 31450423 = 31450476
67 + 31450409 = 31450476
89 + 31450387 = 31450476
107 + 31450369 = 31450476
163 + 31450313 = 31450476
229 + 31450247 = 31450476
257 + 31450219 = 31450476

Showing the first eight; more decompositions exist.
