Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188550, here are decompositions:
- 17 + 188533 = 188550
- 23 + 188527 = 188550
- 31 + 188519 = 188550
- 59 + 188491 = 188550
- 67 + 188483 = 188550
- 107 + 188443 = 188550
- 113 + 188437 = 188550
- 149 + 188401 = 188550
Showing the first eight; more decompositions exist.
