Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451498, here are decompositions:

7 + 31451491 = 31451498
37 + 31451461 = 31451498
61 + 31451437 = 31451498
151 + 31451347 = 31451498
229 + 31451269 = 31451498
349 + 31451149 = 31451498
601 + 31450897 = 31451498
607 + 31450891 = 31451498

Showing the first eight; more decompositions exist.
