Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449764, here are decompositions:

7 + 31449757 = 31449764
13 + 31449751 = 31449764
67 + 31449697 = 31449764
127 + 31449637 = 31449764
193 + 31449571 = 31449764
211 + 31449553 = 31449764
271 + 31449493 = 31449764
523 + 31449241 = 31449764

Showing the first eight; more decompositions exist.
