Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555134, here are decompositions:

41 + 31555093 = 31555134
53 + 31555081 = 31555134
71 + 31555063 = 31555134
73 + 31555061 = 31555134
103 + 31555031 = 31555134
113 + 31555021 = 31555134
173 + 31554961 = 31555134
241 + 31554893 = 31555134

Showing the first eight; more decompositions exist.
