Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464508, here are decompositions:

107 + 31464401 = 31464508
149 + 31464359 = 31464508
167 + 31464341 = 31464508
227 + 31464281 = 31464508
239 + 31464269 = 31464508
359 + 31464149 = 31464508
461 + 31464047 = 31464508
587 + 31463921 = 31464508

Showing the first eight; more decompositions exist.
