Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464902, here are decompositions:

19 + 31464883 = 31464902
193 + 31464709 = 31464902
283 + 31464619 = 31464902
331 + 31464571 = 31464902
409 + 31464493 = 31464902
421 + 31464481 = 31464902
439 + 31464463 = 31464902
463 + 31464439 = 31464902

Showing the first eight; more decompositions exist.
