Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55040, here are decompositions:
- 19 + 55021 = 55040
- 31 + 55009 = 55040
- 61 + 54979 = 55040
- 67 + 54973 = 55040
- 163 + 54877 = 55040
- 211 + 54829 = 55040
- 241 + 54799 = 55040
- 313 + 54727 = 55040
Showing the first eight; more decompositions exist.
