Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144664, here are decompositions:
- 5 + 144659 = 144664
- 53 + 144611 = 144664
- 71 + 144593 = 144664
- 101 + 144563 = 144664
- 167 + 144497 = 144664
- 251 + 144413 = 144664
- 257 + 144407 = 144664
- 281 + 144383 = 144664
Showing the first eight; more decompositions exist.
