Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55478, here are decompositions:
- 37 + 55441 = 55478
- 67 + 55411 = 55478
- 79 + 55399 = 55478
- 97 + 55381 = 55478
- 127 + 55351 = 55478
- 139 + 55339 = 55478
- 229 + 55249 = 55478
- 271 + 55207 = 55478
Showing the first eight; more decompositions exist.
