Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180748, here are decompositions:
- 17 + 180731 = 180748
- 47 + 180701 = 180748
- 101 + 180647 = 180748
- 131 + 180617 = 180748
- 179 + 180569 = 180748
- 251 + 180497 = 180748
- 257 + 180491 = 180748
- 311 + 180437 = 180748
Showing the first eight; more decompositions exist.
