Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990444, here are decompositions:

47 + 990397 = 990444
61 + 990383 = 990444
67 + 990377 = 990444
73 + 990371 = 990444
83 + 990361 = 990444
113 + 990331 = 990444
131 + 990313 = 990444
137 + 990307 = 990444

Showing the first eight; more decompositions exist.
