Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61442, here are decompositions:

61 + 61381 = 61442
79 + 61363 = 61442
103 + 61339 = 61442
109 + 61333 = 61442
151 + 61291 = 61442
181 + 61261 = 61442
211 + 61231 = 61442
313 + 61129 = 61442

Showing the first eight; more decompositions exist.
