Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33144, here are decompositions:
- 31 + 33113 = 33144
- 37 + 33107 = 33144
- 53 + 33091 = 33144
- 61 + 33083 = 33144
- 71 + 33073 = 33144
- 73 + 33071 = 33144
- 107 + 33037 = 33144
- 131 + 33013 = 33144
Showing the first eight; more decompositions exist.
