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.
