Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456662, here are decompositions:

11 + 31456651 = 31456662
23 + 31456639 = 31456662
73 + 31456589 = 31456662
131 + 31456531 = 31456662
233 + 31456429 = 31456662
283 + 31456379 = 31456662
331 + 31456331 = 31456662
383 + 31456279 = 31456662

Showing the first eight; more decompositions exist.
