Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990730, here are decompositions:

11 + 990719 = 990730
23 + 990707 = 990730
131 + 990599 = 990730
137 + 990593 = 990730
227 + 990503 = 990730
233 + 990497 = 990730
347 + 990383 = 990730
353 + 990377 = 990730

Showing the first eight; more decompositions exist.
