Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188468, here are decompositions:
- 31 + 188437 = 188468
- 37 + 188431 = 188468
- 61 + 188407 = 188468
- 67 + 188401 = 188468
- 79 + 188389 = 188468
- 109 + 188359 = 188468
- 151 + 188317 = 188468
- 157 + 188311 = 188468
Showing the first eight; more decompositions exist.
