Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55242, here are decompositions:
- 13 + 55229 = 55242
- 23 + 55219 = 55242
- 29 + 55213 = 55242
- 41 + 55201 = 55242
- 71 + 55171 = 55242
- 79 + 55163 = 55242
- 139 + 55103 = 55242
- 163 + 55079 = 55242
Showing the first eight; more decompositions exist.
