Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68744, here are decompositions:
- 7 + 68737 = 68744
- 31 + 68713 = 68744
- 61 + 68683 = 68744
- 163 + 68581 = 68744
- 223 + 68521 = 68744
- 271 + 68473 = 68744
- 307 + 68437 = 68744
- 373 + 68371 = 68744
Showing the first eight; more decompositions exist.
