Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144946, here are decompositions:
- 5 + 144941 = 144946
- 29 + 144917 = 144946
- 47 + 144899 = 144946
- 59 + 144887 = 144946
- 107 + 144839 = 144946
- 167 + 144779 = 144946
- 173 + 144773 = 144946
- 227 + 144719 = 144946
Showing the first eight; more decompositions exist.
