Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484382, here are decompositions:

5 + 31484377 = 31484382
19 + 31484363 = 31484382
23 + 31484359 = 31484382
29 + 31484353 = 31484382
43 + 31484339 = 31484382
79 + 31484303 = 31484382
101 + 31484281 = 31484382
173 + 31484209 = 31484382

Showing the first eight; more decompositions exist.
