Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550098, here are decompositions:

5 + 31550093 = 31550098
71 + 31550027 = 31550098
131 + 31549967 = 31550098
179 + 31549919 = 31550098
269 + 31549829 = 31550098
317 + 31549781 = 31550098
347 + 31549751 = 31550098
431 + 31549667 = 31550098

Showing the first eight; more decompositions exist.
