Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042780, here are decompositions:

47 + 1042733 = 1042780
71 + 1042709 = 1042780
149 + 1042631 = 1042780
173 + 1042607 = 1042780
197 + 1042583 = 1042780
251 + 1042529 = 1042780
257 + 1042523 = 1042780
293 + 1042487 = 1042780

Showing the first eight; more decompositions exist.
