Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990602, here are decompositions:

3 + 990599 = 990602
13 + 990589 = 990602
43 + 990559 = 990602
73 + 990529 = 990602
79 + 990523 = 990602
139 + 990463 = 990602
241 + 990361 = 990602
271 + 990331 = 990602

Showing the first eight; more decompositions exist.
