Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555064, here are decompositions:

3 + 31555061 = 31555064
43 + 31555021 = 31555064
103 + 31554961 = 31555064
181 + 31554883 = 31555064
223 + 31554841 = 31555064
241 + 31554823 = 31555064
397 + 31554667 = 31555064
433 + 31554631 = 31555064

Showing the first eight; more decompositions exist.
