Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460694, here are decompositions:

17 + 31460677 = 31460694
37 + 31460657 = 31460694
47 + 31460647 = 31460694
113 + 31460581 = 31460694
157 + 31460537 = 31460694
197 + 31460497 = 31460694
211 + 31460483 = 31460694
263 + 31460431 = 31460694

Showing the first eight; more decompositions exist.
