Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607146, here are decompositions:

59 + 31607087 = 31607146
107 + 31607039 = 31607146
149 + 31606997 = 31607146
167 + 31606979 = 31607146
173 + 31606973 = 31607146
227 + 31606919 = 31607146
317 + 31606829 = 31607146
419 + 31606727 = 31607146

Showing the first eight; more decompositions exist.
