Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55618, here are decompositions:
- 29 + 55589 = 55618
- 71 + 55547 = 55618
- 89 + 55529 = 55618
- 107 + 55511 = 55618
- 131 + 55487 = 55618
- 149 + 55469 = 55618
- 179 + 55439 = 55618
- 281 + 55337 = 55618
Showing the first eight; more decompositions exist.
