Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136742, here are decompositions:
- 3 + 136739 = 136742
- 31 + 136711 = 136742
- 139 + 136603 = 136742
- 211 + 136531 = 136742
- 223 + 136519 = 136742
- 241 + 136501 = 136742
- 271 + 136471 = 136742
- 313 + 136429 = 136742
Showing the first eight; more decompositions exist.
