Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122300, here are decompositions:

37 + 122263 = 122300
97 + 122203 = 122300
127 + 122173 = 122300
151 + 122149 = 122300
271 + 122029 = 122300
307 + 121993 = 122300
337 + 121963 = 122300
349 + 121951 = 122300

Showing the first eight; more decompositions exist.
