Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627186, here are decompositions:

53 + 31627133 = 31627186
113 + 31627073 = 31627186
179 + 31627007 = 31627186
293 + 31626893 = 31627186
317 + 31626869 = 31627186
347 + 31626839 = 31627186
359 + 31626827 = 31627186
389 + 31626797 = 31627186

Showing the first eight; more decompositions exist.
