Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569952, here are decompositions:

101 + 31569851 = 31569952
191 + 31569761 = 31569952
251 + 31569701 = 31569952
263 + 31569689 = 31569952
311 + 31569641 = 31569952
353 + 31569599 = 31569952
383 + 31569569 = 31569952
461 + 31569491 = 31569952

Showing the first eight; more decompositions exist.
