Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77042, here are decompositions:
- 13 + 77029 = 77042
- 19 + 77023 = 77042
- 79 + 76963 = 77042
- 211 + 76831 = 77042
- 223 + 76819 = 77042
- 241 + 76801 = 77042
- 271 + 76771 = 77042
- 439 + 76603 = 77042
Showing the first eight; more decompositions exist.
