Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990872, here are decompositions:

31 + 990841 = 990872
73 + 990799 = 990872
139 + 990733 = 990872
199 + 990673 = 990872
229 + 990643 = 990872
241 + 990631 = 990872
283 + 990589 = 990872
313 + 990559 = 990872

Showing the first eight; more decompositions exist.
