Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980550, here are decompositions:

47 + 980503 = 980550
59 + 980491 = 980550
61 + 980489 = 980550
79 + 980471 = 980550
101 + 980449 = 980550
127 + 980423 = 980550
149 + 980401 = 980550
157 + 980393 = 980550

Showing the first eight; more decompositions exist.
