Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990902, here are decompositions:

13 + 990889 = 990902
61 + 990841 = 990902
103 + 990799 = 990902
229 + 990673 = 990902
271 + 990631 = 990902
313 + 990589 = 990902
373 + 990529 = 990902
379 + 990523 = 990902

Showing the first eight; more decompositions exist.
