Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188634, here are decompositions:
- 13 + 188621 = 188634
- 31 + 188603 = 188634
- 71 + 188563 = 188634
- 101 + 188533 = 188634
- 107 + 188527 = 188634
- 151 + 188483 = 188634
- 191 + 188443 = 188634
- 197 + 188437 = 188634
Showing the first eight; more decompositions exist.
