Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009780, here are decompositions:

53 + 1009727 = 1009780
131 + 1009649 = 1009780
137 + 1009643 = 1009780
179 + 1009601 = 1009780
281 + 1009499 = 1009780
293 + 1009487 = 1009780
347 + 1009433 = 1009780
419 + 1009361 = 1009780

Showing the first eight; more decompositions exist.
