Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462966, here are decompositions:

89 + 31462877 = 31462966
173 + 31462793 = 31462966
317 + 31462649 = 31462966
383 + 31462583 = 31462966
389 + 31462577 = 31462966
419 + 31462547 = 31462966
593 + 31462373 = 31462966
617 + 31462349 = 31462966

Showing the first eight; more decompositions exist.
