Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460984, here are decompositions:

7 + 31460977 = 31460984
13 + 31460971 = 31460984
67 + 31460917 = 31460984
151 + 31460833 = 31460984
193 + 31460791 = 31460984
241 + 31460743 = 31460984
283 + 31460701 = 31460984
307 + 31460677 = 31460984

Showing the first eight; more decompositions exist.
