Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462864, here are decompositions:

53 + 31462811 = 31462864
71 + 31462793 = 31462864
107 + 31462757 = 31462864
113 + 31462751 = 31462864
281 + 31462583 = 31462864
311 + 31462553 = 31462864
317 + 31462547 = 31462864
383 + 31462481 = 31462864

Showing the first eight; more decompositions exist.
