Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988886, here are decompositions:

37 + 988849 = 988886
97 + 988789 = 988886
103 + 988783 = 988886
127 + 988759 = 988886
193 + 988693 = 988886
307 + 988579 = 988886
337 + 988549 = 988886
397 + 988489 = 988886

Showing the first eight; more decompositions exist.
