Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526778, here are decompositions:

19 + 526759 = 526778
37 + 526741 = 526778
61 + 526717 = 526778
97 + 526681 = 526778
127 + 526651 = 526778
151 + 526627 = 526778
277 + 526501 = 526778
337 + 526441 = 526778

Showing the first eight; more decompositions exist.
