Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988748, here are decompositions:

37 + 988711 = 988748
67 + 988681 = 988748
97 + 988651 = 988748
157 + 988591 = 988748
199 + 988549 = 988748
331 + 988417 = 988748
601 + 988147 = 988748
619 + 988129 = 988748

Showing the first eight; more decompositions exist.
