Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988772, here are decompositions:

13 + 988759 = 988772
61 + 988711 = 988772
79 + 988693 = 988772
181 + 988591 = 988772
193 + 988579 = 988772
223 + 988549 = 988772
271 + 988501 = 988772
283 + 988489 = 988772

Showing the first eight; more decompositions exist.
