Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991862, here are decompositions:

139 + 991723 = 991862
199 + 991663 = 991862
211 + 991651 = 991862
229 + 991633 = 991862
241 + 991621 = 991862
283 + 991579 = 991862
331 + 991531 = 991862
379 + 991483 = 991862

Showing the first eight; more decompositions exist.
