Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988618, here are decompositions:

11 + 988607 = 988618
41 + 988577 = 988618
47 + 988571 = 988618
107 + 988511 = 988618
179 + 988439 = 988618
251 + 988367 = 988618
347 + 988271 = 988618
401 + 988217 = 988618

Showing the first eight; more decompositions exist.
