Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467662, here are decompositions:

73 + 31467589 = 31467662
103 + 31467559 = 31467662
181 + 31467481 = 31467662
229 + 31467433 = 31467662
433 + 31467229 = 31467662
463 + 31467199 = 31467662
673 + 31466989 = 31467662
769 + 31466893 = 31467662

Showing the first eight; more decompositions exist.
