Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133138, here are decompositions:
- 17 + 133121 = 133138
- 29 + 133109 = 133138
- 41 + 133097 = 133138
- 149 + 132989 = 133138
- 167 + 132971 = 133138
- 191 + 132947 = 133138
- 227 + 132911 = 133138
- 251 + 132887 = 133138
Showing the first eight; more decompositions exist.
