Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990754, here are decompositions:

47 + 990707 = 990754
251 + 990503 = 990754
257 + 990497 = 990754
383 + 990371 = 990754
431 + 990323 = 990754
461 + 990293 = 990754
467 + 990287 = 990754
617 + 990137 = 990754

Showing the first eight; more decompositions exist.
