Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64142, here are decompositions:
- 19 + 64123 = 64142
- 61 + 64081 = 64142
- 79 + 64063 = 64142
- 109 + 64033 = 64142
- 193 + 63949 = 64142
- 229 + 63913 = 64142
- 241 + 63901 = 64142
- 349 + 63793 = 64142
Showing the first eight; more decompositions exist.
