Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484926, here are decompositions:

23 + 31484903 = 31484926
89 + 31484837 = 31484926
149 + 31484777 = 31484926
173 + 31484753 = 31484926
227 + 31484699 = 31484926
383 + 31484543 = 31484926
509 + 31484417 = 31484926
563 + 31484363 = 31484926

Showing the first eight; more decompositions exist.
