Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464416, here are decompositions:

7 + 31464409 = 31464416
19 + 31464397 = 31464416
223 + 31464193 = 31464416
229 + 31464187 = 31464416
337 + 31464079 = 31464416
349 + 31464067 = 31464416
457 + 31463959 = 31464416
523 + 31463893 = 31464416

Showing the first eight; more decompositions exist.
