Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91042, here are decompositions:
- 23 + 91019 = 91042
- 53 + 90989 = 91042
- 71 + 90971 = 91042
- 131 + 90911 = 91042
- 179 + 90863 = 91042
- 239 + 90803 = 91042
- 293 + 90749 = 91042
- 311 + 90731 = 91042
Showing the first eight; more decompositions exist.
