Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74742, here are decompositions:
- 11 + 74731 = 74742
- 13 + 74729 = 74742
- 23 + 74719 = 74742
- 29 + 74713 = 74742
- 43 + 74699 = 74742
- 89 + 74653 = 74742
- 131 + 74611 = 74742
- 181 + 74561 = 74742
Showing the first eight; more decompositions exist.
