Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45144, here are decompositions:
- 5 + 45139 = 45144
- 7 + 45137 = 45144
- 13 + 45131 = 45144
- 17 + 45127 = 45144
- 23 + 45121 = 45144
- 61 + 45083 = 45144
- 67 + 45077 = 45144
- 83 + 45061 = 45144
Showing the first eight; more decompositions exist.
