Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988238, here are decompositions:

7 + 988231 = 988238
19 + 988219 = 988238
109 + 988129 = 988238
127 + 988111 = 988238
241 + 987997 = 988238
499 + 987739 = 988238
541 + 987697 = 988238
607 + 987631 = 988238

Showing the first eight; more decompositions exist.
