Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484932, here are decompositions:

29 + 31484903 = 31484932
131 + 31484801 = 31484932
179 + 31484753 = 31484932
191 + 31484741 = 31484932
233 + 31484699 = 31484932
389 + 31484543 = 31484932
419 + 31484513 = 31484932
569 + 31484363 = 31484932

Showing the first eight; more decompositions exist.
