Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118220, here are decompositions:

7 + 118213 = 118220
31 + 118189 = 118220
73 + 118147 = 118220
127 + 118093 = 118220
139 + 118081 = 118220
163 + 118057 = 118220
229 + 117991 = 118220
241 + 117979 = 118220

Showing the first eight; more decompositions exist.
