Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189744, here are decompositions:
- 11 + 189733 = 189744
- 31 + 189713 = 189744
- 43 + 189701 = 189744
- 47 + 189697 = 189744
- 53 + 189691 = 189744
- 73 + 189671 = 189744
- 83 + 189661 = 189744
- 101 + 189643 = 189744
Showing the first eight; more decompositions exist.
