Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154966, here are decompositions:
- 23 + 154943 = 154966
- 29 + 154937 = 154966
- 83 + 154883 = 154966
- 89 + 154877 = 154966
- 167 + 154799 = 154966
- 179 + 154787 = 154966
- 197 + 154769 = 154966
- 233 + 154733 = 154966
Showing the first eight; more decompositions exist.
