Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045780, here are decompositions:

17 + 1045763 = 1045780
41 + 1045739 = 1045780
53 + 1045727 = 1045780
89 + 1045691 = 1045780
101 + 1045679 = 1045780
137 + 1045643 = 1045780
173 + 1045607 = 1045780
233 + 1045547 = 1045780

Showing the first eight; more decompositions exist.
