Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26390, here are decompositions:
- 3 + 26387 = 26390
- 19 + 26371 = 26390
- 43 + 26347 = 26390
- 73 + 26317 = 26390
- 97 + 26293 = 26390
- 127 + 26263 = 26390
- 139 + 26251 = 26390
- 163 + 26227 = 26390
Showing the first eight; more decompositions exist.
