Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460632, here are decompositions:

23 + 31460609 = 31460632
83 + 31460549 = 31460632
149 + 31460483 = 31460632
191 + 31460441 = 31460632
233 + 31460399 = 31460632
263 + 31460369 = 31460632
293 + 31460339 = 31460632
311 + 31460321 = 31460632

Showing the first eight; more decompositions exist.
