Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988644, here are decompositions:

37 + 988607 = 988644
53 + 988591 = 988644
61 + 988583 = 988644
67 + 988577 = 988644
73 + 988571 = 988644
103 + 988541 = 988644
191 + 988453 = 988644
227 + 988417 = 988644

Showing the first eight; more decompositions exist.
