Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464502, here are decompositions:

59 + 31464443 = 31464502
101 + 31464401 = 31464502
233 + 31464269 = 31464502
269 + 31464233 = 31464502
353 + 31464149 = 31464502
359 + 31464143 = 31464502
593 + 31463909 = 31464502
653 + 31463849 = 31464502

Showing the first eight; more decompositions exist.
