Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484698, here are decompositions:

71 + 31484627 = 31484698
281 + 31484417 = 31484698
359 + 31484339 = 31484698
431 + 31484267 = 31484698
461 + 31484237 = 31484698
491 + 31484207 = 31484698
521 + 31484177 = 31484698
569 + 31484129 = 31484698

Showing the first eight; more decompositions exist.
