Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142956, here are decompositions:
- 7 + 142949 = 142956
- 17 + 142939 = 142956
- 53 + 142903 = 142956
- 59 + 142897 = 142956
- 83 + 142873 = 142956
- 89 + 142867 = 142956
- 157 + 142799 = 142956
- 167 + 142789 = 142956
Showing the first eight; more decompositions exist.
