Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55388, here are decompositions:
- 7 + 55381 = 55388
- 37 + 55351 = 55388
- 97 + 55291 = 55388
- 139 + 55249 = 55388
- 181 + 55207 = 55388
- 241 + 55147 = 55388
- 271 + 55117 = 55388
- 331 + 55057 = 55388
Showing the first eight; more decompositions exist.
