Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123190, here are decompositions:

47 + 123143 = 123190
107 + 123083 = 123190
113 + 123077 = 123190
131 + 123059 = 123190
173 + 123017 = 123190
227 + 122963 = 123190
233 + 122957 = 123190
251 + 122939 = 123190

Showing the first eight; more decompositions exist.
