Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74772, here are decompositions:
- 11 + 74761 = 74772
- 13 + 74759 = 74772
- 41 + 74731 = 74772
- 43 + 74729 = 74772
- 53 + 74719 = 74772
- 59 + 74713 = 74772
- 73 + 74699 = 74772
- 149 + 74623 = 74772
Showing the first eight; more decompositions exist.
