Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042158, here are decompositions:
- 17 + 1042141 = 1042158
- 37 + 1042121 = 1042158
- 59 + 1042099 = 1042158
- 67 + 1042091 = 1042158
- 71 + 1042087 = 1042158
- 137 + 1042021 = 1042158
- 157 + 1042001 = 1042158
- 167 + 1041991 = 1042158
Showing the first eight; more decompositions exist.
