Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55580, here are decompositions:
- 79 + 55501 = 55580
- 139 + 55441 = 55580
- 181 + 55399 = 55580
- 199 + 55381 = 55580
- 229 + 55351 = 55580
- 241 + 55339 = 55580
- 331 + 55249 = 55580
- 337 + 55243 = 55580
Showing the first eight; more decompositions exist.
