Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33138, here are decompositions:
- 19 + 33119 = 33138
- 31 + 33107 = 33138
- 47 + 33091 = 33138
- 67 + 33071 = 33138
- 89 + 33049 = 33138
- 101 + 33037 = 33138
- 109 + 33029 = 33138
- 139 + 32999 = 33138
Showing the first eight; more decompositions exist.
