Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999278, here are decompositions:

61 + 999217 = 999278
79 + 999199 = 999278
97 + 999181 = 999278
109 + 999169 = 999278
211 + 999067 = 999278
229 + 999049 = 999278
271 + 999007 = 999278
331 + 998947 = 999278

Showing the first eight; more decompositions exist.
