Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990724, here are decompositions:

5 + 990719 = 990724
17 + 990707 = 990724
131 + 990593 = 990724
227 + 990497 = 990724
347 + 990377 = 990724
353 + 990371 = 990724
401 + 990323 = 990724
431 + 990293 = 990724

Showing the first eight; more decompositions exist.
