Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997226, here are decompositions:

7 + 997219 = 997226
19 + 997207 = 997226
73 + 997153 = 997226
79 + 997147 = 997226
103 + 997123 = 997226
127 + 997099 = 997226
157 + 997069 = 997226
367 + 996859 = 997226

Showing the first eight; more decompositions exist.
