Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451376, here are decompositions:

29 + 31451347 = 31451376
53 + 31451323 = 31451376
79 + 31451297 = 31451376
83 + 31451293 = 31451376
107 + 31451269 = 31451376
137 + 31451239 = 31451376
157 + 31451219 = 31451376
167 + 31451209 = 31451376

Showing the first eight; more decompositions exist.
