Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567772, here are decompositions:

3 + 31567769 = 31567772
31 + 31567741 = 31567772
43 + 31567729 = 31567772
73 + 31567699 = 31567772
79 + 31567693 = 31567772
151 + 31567621 = 31567772
541 + 31567231 = 31567772
619 + 31567153 = 31567772

Showing the first eight; more decompositions exist.
