Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460866, here are decompositions:

29 + 31460837 = 31460866
83 + 31460783 = 31460866
137 + 31460729 = 31460866
149 + 31460717 = 31460866
257 + 31460609 = 31460866
317 + 31460549 = 31460866
383 + 31460483 = 31460866
467 + 31460399 = 31460866

Showing the first eight; more decompositions exist.
