Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484668, here are decompositions:

41 + 31484627 = 31484668
251 + 31484417 = 31484668
401 + 31484267 = 31484668
431 + 31484237 = 31484668
461 + 31484207 = 31484668
491 + 31484177 = 31484668
587 + 31484081 = 31484668
599 + 31484069 = 31484668

Showing the first eight; more decompositions exist.
