Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16142, here are decompositions:
- 3 + 16139 = 16142
- 31 + 16111 = 16142
- 73 + 16069 = 16142
- 79 + 16063 = 16142
- 109 + 16033 = 16142
- 151 + 15991 = 16142
- 223 + 15919 = 16142
- 229 + 15913 = 16142
Showing the first eight; more decompositions exist.
