Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75642, here are decompositions:
- 13 + 75629 = 75642
- 23 + 75619 = 75642
- 31 + 75611 = 75642
- 59 + 75583 = 75642
- 71 + 75571 = 75642
- 89 + 75553 = 75642
- 101 + 75541 = 75642
- 103 + 75539 = 75642
Showing the first eight; more decompositions exist.
