Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460638, here are decompositions:

29 + 31460609 = 31460638
89 + 31460549 = 31460638
101 + 31460537 = 31460638
197 + 31460441 = 31460638
239 + 31460399 = 31460638
269 + 31460369 = 31460638
317 + 31460321 = 31460638
347 + 31460291 = 31460638

Showing the first eight; more decompositions exist.
