Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997238, here are decompositions:

19 + 997219 = 997238
31 + 997207 = 997238
37 + 997201 = 997238
97 + 997141 = 997238
127 + 997111 = 997238
139 + 997099 = 997238
157 + 997081 = 997238
181 + 997057 = 997238

Showing the first eight; more decompositions exist.
