Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484746, here are decompositions:

5 + 31484741 = 31484746
47 + 31484699 = 31484746
233 + 31484513 = 31484746
383 + 31484363 = 31484746
443 + 31484303 = 31484746
479 + 31484267 = 31484746
509 + 31484237 = 31484746
569 + 31484177 = 31484746

Showing the first eight; more decompositions exist.
