Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99142, here are decompositions:
- 3 + 99139 = 99142
- 5 + 99137 = 99142
- 11 + 99131 = 99142
- 23 + 99119 = 99142
- 53 + 99089 = 99142
- 59 + 99083 = 99142
- 89 + 99053 = 99142
- 101 + 99041 = 99142
Showing the first eight; more decompositions exist.
