Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482842, here are decompositions:

3 + 31482839 = 31482842
19 + 31482823 = 31482842
43 + 31482799 = 31482842
199 + 31482643 = 31482842
211 + 31482631 = 31482842
229 + 31482613 = 31482842
283 + 31482559 = 31482842
331 + 31482511 = 31482842

Showing the first eight; more decompositions exist.
