Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567274, here are decompositions:

3 + 31567271 = 31567274
7 + 31567267 = 31567274
43 + 31567231 = 31567274
61 + 31567213 = 31567274
307 + 31566967 = 31567274
373 + 31566901 = 31567274
457 + 31566817 = 31567274
643 + 31566631 = 31567274

Showing the first eight; more decompositions exist.
