Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124272, here are decompositions:

23 + 124249 = 124272
41 + 124231 = 124272
59 + 124213 = 124272
73 + 124199 = 124272
79 + 124193 = 124272
89 + 124183 = 124272
101 + 124171 = 124272
139 + 124133 = 124272

Showing the first eight; more decompositions exist.
