Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90742, here are decompositions:
- 11 + 90731 = 90742
- 83 + 90659 = 90742
- 101 + 90641 = 90742
- 269 + 90473 = 90742
- 383 + 90359 = 90742
- 389 + 90353 = 90742
- 461 + 90281 = 90742
- 479 + 90263 = 90742
Showing the first eight; more decompositions exist.
