Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463654, here are decompositions:

67 + 31463587 = 31463654
127 + 31463527 = 31463654
337 + 31463317 = 31463654
373 + 31463281 = 31463654
457 + 31463197 = 31463654
487 + 31463167 = 31463654
571 + 31463083 = 31463654
577 + 31463077 = 31463654

Showing the first eight; more decompositions exist.
