Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548922, here are decompositions:

173 + 31548749 = 31548922
179 + 31548743 = 31548922
263 + 31548659 = 31548922
269 + 31548653 = 31548922
281 + 31548641 = 31548922
359 + 31548563 = 31548922
389 + 31548533 = 31548922
401 + 31548521 = 31548922

Showing the first eight; more decompositions exist.
