Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020278, here are decompositions:

19 + 1020259 = 1020278
31 + 1020247 = 1020278
199 + 1020079 = 1020278
229 + 1020049 = 1020278
241 + 1020037 = 1020278
271 + 1020007 = 1020278
277 + 1020001 = 1020278
307 + 1019971 = 1020278

Showing the first eight; more decompositions exist.
