Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39340, here are decompositions:
- 17 + 39323 = 39340
- 23 + 39317 = 39340
- 47 + 39293 = 39340
- 89 + 39251 = 39340
- 101 + 39239 = 39340
- 107 + 39233 = 39340
- 113 + 39227 = 39340
- 131 + 39209 = 39340
Showing the first eight; more decompositions exist.
