Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84542, here are decompositions:
- 19 + 84523 = 84542
- 43 + 84499 = 84542
- 61 + 84481 = 84542
- 79 + 84463 = 84542
- 151 + 84391 = 84542
- 193 + 84349 = 84542
- 223 + 84319 = 84542
- 229 + 84313 = 84542
Showing the first eight; more decompositions exist.
