Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541184, here are decompositions:

5 + 31541179 = 31541184
11 + 31541173 = 31541184
23 + 31541161 = 31541184
43 + 31541141 = 31541184
67 + 31541117 = 31541184
71 + 31541113 = 31541184
83 + 31541101 = 31541184
113 + 31541071 = 31541184

Showing the first eight; more decompositions exist.
