Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502184, here are decompositions:

23 + 31502161 = 31502184
37 + 31502147 = 31502184
53 + 31502131 = 31502184
71 + 31502113 = 31502184
101 + 31502083 = 31502184
227 + 31501957 = 31502184
271 + 31501913 = 31502184
277 + 31501907 = 31502184

Showing the first eight; more decompositions exist.
