Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005814, here are decompositions:

53 + 1005761 = 1005814
113 + 1005701 = 1005814
137 + 1005677 = 1005814
167 + 1005647 = 1005814
197 + 1005617 = 1005814
233 + 1005581 = 1005814
263 + 1005551 = 1005814
311 + 1005503 = 1005814

Showing the first eight; more decompositions exist.
