Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447762, here are decompositions:

11 + 31447751 = 31447762
89 + 31447673 = 31447762
131 + 31447631 = 31447762
179 + 31447583 = 31447762
233 + 31447529 = 31447762
383 + 31447379 = 31447762
461 + 31447301 = 31447762
509 + 31447253 = 31447762

Showing the first eight; more decompositions exist.
