Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55578, here are decompositions:
- 31 + 55547 = 55578
- 37 + 55541 = 55578
- 67 + 55511 = 55578
- 109 + 55469 = 55578
- 137 + 55441 = 55578
- 139 + 55439 = 55578
- 167 + 55411 = 55578
- 179 + 55399 = 55578
Showing the first eight; more decompositions exist.
