Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55620, here are decompositions:
- 11 + 55609 = 55620
- 17 + 55603 = 55620
- 31 + 55589 = 55620
- 41 + 55579 = 55620
- 73 + 55547 = 55620
- 79 + 55541 = 55620
- 109 + 55511 = 55620
- 151 + 55469 = 55620
Showing the first eight; more decompositions exist.
