Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61142, here are decompositions:

13 + 61129 = 61142
43 + 61099 = 61142
181 + 60961 = 61142
199 + 60943 = 61142
223 + 60919 = 61142
229 + 60913 = 61142
241 + 60901 = 61142
283 + 60859 = 61142

Showing the first eight; more decompositions exist.
