Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550632, here are decompositions:

5 + 31550627 = 31550632
59 + 31550573 = 31550632
89 + 31550543 = 31550632
101 + 31550531 = 31550632
173 + 31550459 = 31550632
293 + 31550339 = 31550632
419 + 31550213 = 31550632
431 + 31550201 = 31550632

Showing the first eight; more decompositions exist.
