Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121042, here are decompositions:
- 3 + 121039 = 121042
- 23 + 121019 = 121042
- 29 + 121013 = 121042
- 41 + 121001 = 121042
- 101 + 120941 = 121042
- 113 + 120929 = 121042
- 179 + 120863 = 121042
- 191 + 120851 = 121042
Showing the first eight; more decompositions exist.
