Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462654, here are decompositions:

5 + 31462649 = 31462654
71 + 31462583 = 31462654
101 + 31462553 = 31462654
107 + 31462547 = 31462654
173 + 31462481 = 31462654
281 + 31462373 = 31462654
521 + 31462133 = 31462654
647 + 31462007 = 31462654

Showing the first eight; more decompositions exist.
