Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55138, here are decompositions:
- 11 + 55127 = 55138
- 29 + 55109 = 55138
- 59 + 55079 = 55138
- 89 + 55049 = 55138
- 137 + 55001 = 55138
- 179 + 54959 = 55138
- 197 + 54941 = 55138
- 257 + 54881 = 55138
Showing the first eight; more decompositions exist.
