Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460346, here are decompositions:

7 + 31460339 = 31460346
17 + 31460329 = 31460346
53 + 31460293 = 31460346
67 + 31460279 = 31460346
79 + 31460267 = 31460346
83 + 31460263 = 31460346
149 + 31460197 = 31460346
173 + 31460173 = 31460346

Showing the first eight; more decompositions exist.
