Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1052780, here are decompositions:

13 + 1052767 = 1052780
37 + 1052743 = 1052780
61 + 1052719 = 1052780
73 + 1052707 = 1052780
151 + 1052629 = 1052780
229 + 1052551 = 1052780
307 + 1052473 = 1052780
349 + 1052431 = 1052780

Showing the first eight; more decompositions exist.
