Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555060, here are decompositions:

29 + 31555031 = 31555060
41 + 31555019 = 31555060
113 + 31554947 = 31555060
167 + 31554893 = 31555060
197 + 31554863 = 31555060
263 + 31554797 = 31555060
269 + 31554791 = 31555060
311 + 31554749 = 31555060

Showing the first eight; more decompositions exist.
