Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028978, here are decompositions:

37 + 1028941 = 1028978
229 + 1028749 = 1028978
241 + 1028737 = 1028978
331 + 1028647 = 1028978
397 + 1028581 = 1028978
409 + 1028569 = 1028978
421 + 1028557 = 1028978
499 + 1028479 = 1028978

Showing the first eight; more decompositions exist.
