Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972220, here are decompositions:

23 + 972197 = 972220
59 + 972161 = 972220
83 + 972137 = 972220
89 + 972131 = 972220
101 + 972119 = 972220
107 + 972113 = 972220
149 + 972071 = 972220
173 + 972047 = 972220

Showing the first eight; more decompositions exist.
