Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75738, here are decompositions:
- 7 + 75731 = 75738
- 17 + 75721 = 75738
- 29 + 75709 = 75738
- 31 + 75707 = 75738
- 59 + 75679 = 75738
- 79 + 75659 = 75738
- 97 + 75641 = 75738
- 109 + 75629 = 75738
Showing the first eight; more decompositions exist.
