Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484896, here are decompositions:

59 + 31484837 = 31484896
197 + 31484699 = 31484896
269 + 31484627 = 31484896
353 + 31484543 = 31484896
383 + 31484513 = 31484896
479 + 31484417 = 31484896
557 + 31484339 = 31484896
593 + 31484303 = 31484896

Showing the first eight; more decompositions exist.
