Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451426, here are decompositions:

43 + 31451383 = 31451426
79 + 31451347 = 31451426
103 + 31451323 = 31451426
157 + 31451269 = 31451426
277 + 31451149 = 31451426
379 + 31451047 = 31451426
397 + 31451029 = 31451426
547 + 31450879 = 31451426

Showing the first eight; more decompositions exist.
