Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55238, here are decompositions:
- 19 + 55219 = 55238
- 31 + 55207 = 55238
- 37 + 55201 = 55238
- 67 + 55171 = 55238
- 181 + 55057 = 55238
- 229 + 55009 = 55238
- 331 + 54907 = 55238
- 409 + 54829 = 55238
Showing the first eight; more decompositions exist.
