Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538122, here are decompositions:

59 + 31538063 = 31538122
89 + 31538033 = 31538122
233 + 31537889 = 31538122
251 + 31537871 = 31538122
263 + 31537859 = 31538122
401 + 31537721 = 31538122
431 + 31537691 = 31538122
491 + 31537631 = 31538122

Showing the first eight; more decompositions exist.
