Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189936, here are decompositions:
- 7 + 189929 = 189936
- 23 + 189913 = 189936
- 59 + 189877 = 189936
- 83 + 189853 = 189936
- 113 + 189823 = 189936
- 137 + 189799 = 189936
- 139 + 189797 = 189936
- 179 + 189757 = 189936
Showing the first eight; more decompositions exist.
