Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567764, here are decompositions:

23 + 31567741 = 31567764
47 + 31567717 = 31567764
71 + 31567693 = 31567764
83 + 31567681 = 31567764
127 + 31567637 = 31567764
211 + 31567553 = 31567764
251 + 31567513 = 31567764
313 + 31567451 = 31567764

Showing the first eight; more decompositions exist.
