Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75684, here are decompositions:
- 5 + 75679 = 75684
- 31 + 75653 = 75684
- 43 + 75641 = 75684
- 67 + 75617 = 75684
- 73 + 75611 = 75684
- 101 + 75583 = 75684
- 107 + 75577 = 75684
- 113 + 75571 = 75684
Showing the first eight; more decompositions exist.
