Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549102, here are decompositions:

3 + 31549099 = 31549102
59 + 31549043 = 31549102
83 + 31549019 = 31549102
149 + 31548953 = 31549102
353 + 31548749 = 31549102
359 + 31548743 = 31549102
443 + 31548659 = 31549102
449 + 31548653 = 31549102

Showing the first eight; more decompositions exist.
