Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451484, here are decompositions:

23 + 31451461 = 31451484
47 + 31451437 = 31451484
101 + 31451383 = 31451484
137 + 31451347 = 31451484
191 + 31451293 = 31451484
223 + 31451261 = 31451484
283 + 31451201 = 31451484
313 + 31451171 = 31451484

Showing the first eight; more decompositions exist.
