Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184642, here are decompositions:
- 11 + 184631 = 184642
- 71 + 184571 = 184642
- 83 + 184559 = 184642
- 89 + 184553 = 184642
- 131 + 184511 = 184642
- 179 + 184463 = 184642
- 233 + 184409 = 184642
- 383 + 184259 = 184642
Showing the first eight; more decompositions exist.
