Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464942, here are decompositions:

59 + 31464883 = 31464942
211 + 31464731 = 31464942
233 + 31464709 = 31464942
241 + 31464701 = 31464942
293 + 31464649 = 31464942
433 + 31464509 = 31464942
449 + 31464493 = 31464942
461 + 31464481 = 31464942

Showing the first eight; more decompositions exist.
