Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133790, here are decompositions:
- 67 + 133723 = 133790
- 73 + 133717 = 133790
- 79 + 133711 = 133790
- 157 + 133633 = 133790
- 193 + 133597 = 133790
- 271 + 133519 = 133790
- 373 + 133417 = 133790
- 439 + 133351 = 133790
Showing the first eight; more decompositions exist.
