Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61240, here are decompositions:

17 + 61223 = 61240
29 + 61211 = 61240
71 + 61169 = 61240
89 + 61151 = 61240
149 + 61091 = 61240
197 + 61043 = 61240
233 + 61007 = 61240
239 + 61001 = 61240

Showing the first eight; more decompositions exist.
