Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988730, here are decompositions:

3 + 988727 = 988730
19 + 988711 = 988730
37 + 988693 = 988730
79 + 988651 = 988730
139 + 988591 = 988730
151 + 988579 = 988730
181 + 988549 = 988730
229 + 988501 = 988730

Showing the first eight; more decompositions exist.
