Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61358, here are decompositions:

19 + 61339 = 61358
61 + 61297 = 61358
67 + 61291 = 61358
97 + 61261 = 61358
127 + 61231 = 61358
229 + 61129 = 61358
307 + 61051 = 61358
331 + 61027 = 61358

Showing the first eight; more decompositions exist.
