Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66242, here are decompositions:
- 3 + 66239 = 66242
- 73 + 66169 = 66242
- 139 + 66103 = 66242
- 313 + 65929 = 66242
- 433 + 65809 = 66242
- 523 + 65719 = 66242
- 541 + 65701 = 66242
- 613 + 65629 = 66242
Showing the first eight; more decompositions exist.
