Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85742, here are decompositions:
- 31 + 85711 = 85742
- 73 + 85669 = 85742
- 103 + 85639 = 85742
- 193 + 85549 = 85742
- 211 + 85531 = 85742
- 229 + 85513 = 85742
- 313 + 85429 = 85742
- 331 + 85411 = 85742
Showing the first eight; more decompositions exist.
