Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988774, here are decompositions:

11 + 988763 = 988774
41 + 988733 = 988774
47 + 988727 = 988774
113 + 988661 = 988774
131 + 988643 = 988774
167 + 988607 = 988774
191 + 988583 = 988774
197 + 988577 = 988774

Showing the first eight; more decompositions exist.
