Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85722, here are decompositions:
- 5 + 85717 = 85722
- 11 + 85711 = 85722
- 19 + 85703 = 85722
- 31 + 85691 = 85722
- 53 + 85669 = 85722
- 61 + 85661 = 85722
- 79 + 85643 = 85722
- 83 + 85639 = 85722
Showing the first eight; more decompositions exist.
