Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988650, here are decompositions:

7 + 988643 = 988650
43 + 988607 = 988650
59 + 988591 = 988650
67 + 988583 = 988650
71 + 988579 = 988650
73 + 988577 = 988650
79 + 988571 = 988650
101 + 988549 = 988650

Showing the first eight; more decompositions exist.
