Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55386, here are decompositions:
- 5 + 55381 = 55386
- 13 + 55373 = 55386
- 43 + 55343 = 55386
- 47 + 55339 = 55386
- 53 + 55333 = 55386
- 73 + 55313 = 55386
- 127 + 55259 = 55386
- 137 + 55249 = 55386
Showing the first eight; more decompositions exist.
