Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627174, here are decompositions:

23 + 31627151 = 31627174
41 + 31627133 = 31627174
53 + 31627121 = 31627174
83 + 31627091 = 31627174
101 + 31627073 = 31627174
167 + 31627007 = 31627174
197 + 31626977 = 31627174
281 + 31626893 = 31627174

Showing the first eight; more decompositions exist.
