Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 52642, here are decompositions:
- 3 + 52639 = 52642
- 11 + 52631 = 52642
- 59 + 52583 = 52642
- 71 + 52571 = 52642
- 89 + 52553 = 52642
- 101 + 52541 = 52642
- 113 + 52529 = 52642
- 131 + 52511 = 52642
Showing the first eight; more decompositions exist.
