Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627210, here are decompositions:

59 + 31627151 = 31627210
89 + 31627121 = 31627210
137 + 31627073 = 31627210
233 + 31626977 = 31627210
311 + 31626899 = 31627210
317 + 31626893 = 31627210
353 + 31626857 = 31627210
383 + 31626827 = 31627210

Showing the first eight; more decompositions exist.
