Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144976, here are decompositions:
- 3 + 144973 = 144976
- 59 + 144917 = 144976
- 89 + 144887 = 144976
- 137 + 144839 = 144976
- 197 + 144779 = 144976
- 239 + 144737 = 144976
- 257 + 144719 = 144976
- 317 + 144659 = 144976
Showing the first eight; more decompositions exist.
