Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951220, here are decompositions:

59 + 951161 = 951220
89 + 951131 = 951220
113 + 951107 = 951220
131 + 951089 = 951220
167 + 951053 = 951220
173 + 951047 = 951220
191 + 951029 = 951220
197 + 951023 = 951220

Showing the first eight; more decompositions exist.
