Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159042, here are decompositions:
- 19 + 159023 = 159042
- 29 + 159013 = 159042
- 61 + 158981 = 159042
- 83 + 158959 = 159042
- 101 + 158941 = 159042
- 179 + 158863 = 159042
- 193 + 158849 = 159042
- 199 + 158843 = 159042
Showing the first eight; more decompositions exist.
