Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990736, here are decompositions:

3 + 990733 = 990736
17 + 990719 = 990736
29 + 990707 = 990736
137 + 990599 = 990736
233 + 990503 = 990736
239 + 990497 = 990736
347 + 990389 = 990736
353 + 990383 = 990736

Showing the first eight; more decompositions exist.
