Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55288, here are decompositions:
- 29 + 55259 = 55288
- 59 + 55229 = 55288
- 71 + 55217 = 55288
- 179 + 55109 = 55288
- 227 + 55061 = 55288
- 239 + 55049 = 55288
- 347 + 54941 = 55288
- 419 + 54869 = 55288
Showing the first eight; more decompositions exist.
