Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42772, here are decompositions:
- 5 + 42767 = 42772
- 29 + 42743 = 42772
- 53 + 42719 = 42772
- 71 + 42701 = 42772
- 83 + 42689 = 42772
- 89 + 42683 = 42772
- 131 + 42641 = 42772
- 239 + 42533 = 42772
Showing the first eight; more decompositions exist.
