Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484962, here are decompositions:

59 + 31484903 = 31484962
191 + 31484771 = 31484962
251 + 31484711 = 31484962
263 + 31484699 = 31484962
419 + 31484543 = 31484962
449 + 31484513 = 31484962
599 + 31484363 = 31484962
659 + 31484303 = 31484962

Showing the first eight; more decompositions exist.
