Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484392, here are decompositions:

29 + 31484363 = 31484392
53 + 31484339 = 31484392
89 + 31484303 = 31484392
263 + 31484129 = 31484392
311 + 31484081 = 31484392
479 + 31483913 = 31484392
503 + 31483889 = 31484392
509 + 31483883 = 31484392

Showing the first eight; more decompositions exist.
