Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86744, here are decompositions:
- 67 + 86677 = 86744
- 157 + 86587 = 86744
- 211 + 86533 = 86744
- 277 + 86467 = 86744
- 283 + 86461 = 86744
- 331 + 86413 = 86744
- 373 + 86371 = 86744
- 421 + 86323 = 86744
Showing the first eight; more decompositions exist.
