Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018862, here are decompositions:

3 + 1018859 = 1018862
73 + 1018789 = 1018862
151 + 1018711 = 1018862
193 + 1018669 = 1018862
211 + 1018651 = 1018862
241 + 1018621 = 1018862
349 + 1018513 = 1018862
373 + 1018489 = 1018862

Showing the first eight; more decompositions exist.
