Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627204, here are decompositions:

3 + 31627201 = 31627204
53 + 31627151 = 31627204
71 + 31627133 = 31627204
83 + 31627121 = 31627204
113 + 31627091 = 31627204
131 + 31627073 = 31627204
197 + 31627007 = 31627204
227 + 31626977 = 31627204

Showing the first eight; more decompositions exist.
