Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189750, here are decompositions:
- 7 + 189743 = 189750
- 17 + 189733 = 189750
- 37 + 189713 = 189750
- 53 + 189697 = 189750
- 59 + 189691 = 189750
- 79 + 189671 = 189750
- 89 + 189661 = 189750
- 97 + 189653 = 189750
Showing the first eight; more decompositions exist.
