Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992780, here are decompositions:

3 + 992777 = 992780
43 + 992737 = 992780
73 + 992707 = 992780
79 + 992701 = 992780
157 + 992623 = 992780
241 + 992539 = 992780
331 + 992449 = 992780
409 + 992371 = 992780

Showing the first eight; more decompositions exist.
