Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534180, here are decompositions:

11 + 31534169 = 31534180
59 + 31534121 = 31534180
101 + 31534079 = 31534180
107 + 31534073 = 31534180
113 + 31534067 = 31534180
257 + 31533923 = 31534180
269 + 31533911 = 31534180
347 + 31533833 = 31534180

Showing the first eight; more decompositions exist.
