Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86426, here are decompositions:
- 3 + 86423 = 86426
- 13 + 86413 = 86426
- 37 + 86389 = 86426
- 73 + 86353 = 86426
- 103 + 86323 = 86426
- 139 + 86287 = 86426
- 157 + 86269 = 86426
- 163 + 86263 = 86426
Showing the first eight; more decompositions exist.
