Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61642, here are decompositions:
- 5 + 61637 = 61642
- 11 + 61631 = 61642
- 29 + 61613 = 61642
- 59 + 61583 = 61642
- 83 + 61559 = 61642
- 89 + 61553 = 61642
- 131 + 61511 = 61642
- 149 + 61493 = 61642
Showing the first eight; more decompositions exist.
