Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124290, here are decompositions:

13 + 124277 = 124290
41 + 124249 = 124290
43 + 124247 = 124290
59 + 124231 = 124290
97 + 124193 = 124290
107 + 124183 = 124290
109 + 124181 = 124290
137 + 124153 = 124290

Showing the first eight; more decompositions exist.
