Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55320, here are decompositions:
- 7 + 55313 = 55320
- 29 + 55291 = 55320
- 61 + 55259 = 55320
- 71 + 55249 = 55320
- 101 + 55219 = 55320
- 103 + 55217 = 55320
- 107 + 55213 = 55320
- 113 + 55207 = 55320
Showing the first eight; more decompositions exist.
