Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61238, here are decompositions:

7 + 61231 = 61238
97 + 61141 = 61238
109 + 61129 = 61238
139 + 61099 = 61238
181 + 61057 = 61238
211 + 61027 = 61238
277 + 60961 = 61238
337 + 60901 = 61238

Showing the first eight; more decompositions exist.
