Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464962, here are decompositions:

79 + 31464883 = 31464962
181 + 31464781 = 31464962
313 + 31464649 = 31464962
499 + 31464463 = 31464962
523 + 31464439 = 31464962
541 + 31464421 = 31464962
691 + 31464271 = 31464962
769 + 31464193 = 31464962

Showing the first eight; more decompositions exist.
