Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144994, here are decompositions:
- 11 + 144983 = 144994
- 53 + 144941 = 144994
- 107 + 144887 = 144994
- 257 + 144737 = 144994
- 263 + 144731 = 144994
- 293 + 144701 = 144994
- 383 + 144611 = 144994
- 401 + 144593 = 144994
Showing the first eight; more decompositions exist.
