Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55420, here are decompositions:
- 47 + 55373 = 55420
- 83 + 55337 = 55420
- 89 + 55331 = 55420
- 107 + 55313 = 55420
- 191 + 55229 = 55420
- 257 + 55163 = 55420
- 293 + 55127 = 55420
- 311 + 55109 = 55420
Showing the first eight; more decompositions exist.
