Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464898, here are decompositions:

71 + 31464827 = 31464898
89 + 31464809 = 31464898
167 + 31464731 = 31464898
197 + 31464701 = 31464898
281 + 31464617 = 31464898
317 + 31464581 = 31464898
389 + 31464509 = 31464898
557 + 31464341 = 31464898

Showing the first eight; more decompositions exist.
