Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990830, here are decompositions:

31 + 990799 = 990830
97 + 990733 = 990830
157 + 990673 = 990830
193 + 990637 = 990830
199 + 990631 = 990830
241 + 990589 = 990830
271 + 990559 = 990830
283 + 990547 = 990830

Showing the first eight; more decompositions exist.
