Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450936, here are decompositions:

89 + 31450847 = 31450936
107 + 31450829 = 31450936
113 + 31450823 = 31450936
149 + 31450787 = 31450936
173 + 31450763 = 31450936
197 + 31450739 = 31450936
269 + 31450667 = 31450936
317 + 31450619 = 31450936

Showing the first eight; more decompositions exist.
