Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988648, here are decompositions:

5 + 988643 = 988648
41 + 988607 = 988648
71 + 988577 = 988648
107 + 988541 = 988648
137 + 988511 = 988648
239 + 988409 = 988648
281 + 988367 = 988648
431 + 988217 = 988648

Showing the first eight; more decompositions exist.
