Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464702, here are decompositions:

53 + 31464649 = 31464702
83 + 31464619 = 31464702
131 + 31464571 = 31464702
193 + 31464509 = 31464702
239 + 31464463 = 31464702
251 + 31464451 = 31464702
263 + 31464439 = 31464702
281 + 31464421 = 31464702

Showing the first eight; more decompositions exist.
