Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55642, here are decompositions:
- 3 + 55639 = 55642
- 11 + 55631 = 55642
- 23 + 55619 = 55642
- 53 + 55589 = 55642
- 101 + 55541 = 55642
- 113 + 55529 = 55642
- 131 + 55511 = 55642
- 173 + 55469 = 55642
Showing the first eight; more decompositions exist.
