Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488826, here are decompositions:

29 + 31488797 = 31488826
59 + 31488767 = 31488826
179 + 31488647 = 31488826
263 + 31488563 = 31488826
269 + 31488557 = 31488826
419 + 31488407 = 31488826
503 + 31488323 = 31488826
569 + 31488257 = 31488826

Showing the first eight; more decompositions exist.
