Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55406, here are decompositions:
- 7 + 55399 = 55406
- 67 + 55339 = 55406
- 73 + 55333 = 55406
- 157 + 55249 = 55406
- 163 + 55243 = 55406
- 193 + 55213 = 55406
- 199 + 55207 = 55406
- 349 + 55057 = 55406
Showing the first eight; more decompositions exist.
