Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5142, here are decompositions:
- 23 + 5119 = 5142
- 29 + 5113 = 5142
- 41 + 5101 = 5142
- 43 + 5099 = 5142
- 61 + 5081 = 5142
- 83 + 5059 = 5142
- 103 + 5039 = 5142
- 131 + 5011 = 5142
Showing the first eight; more decompositions exist.
