Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55668, here are decompositions:
- 5 + 55663 = 55668
- 7 + 55661 = 55668
- 29 + 55639 = 55668
- 37 + 55631 = 55668
- 47 + 55621 = 55668
- 59 + 55609 = 55668
- 79 + 55589 = 55668
- 89 + 55579 = 55668
Showing the first eight; more decompositions exist.
