Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 992778, here are decompositions:

41 + 992737 = 992778
71 + 992707 = 992778
89 + 992689 = 992778
229 + 992549 = 992778
239 + 992539 = 992778
257 + 992521 = 992778
317 + 992461 = 992778
337 + 992441 = 992778

Showing the first eight; more decompositions exist.
