Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484562, here are decompositions:

19 + 31484543 = 31484562
29 + 31484533 = 31484562
59 + 31484503 = 31484562
101 + 31484461 = 31484562
113 + 31484449 = 31484562
149 + 31484413 = 31484562
199 + 31484363 = 31484562
223 + 31484339 = 31484562

Showing the first eight; more decompositions exist.
