Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55080, here are decompositions:
- 7 + 55073 = 55080
- 19 + 55061 = 55080
- 23 + 55057 = 55080
- 29 + 55051 = 55080
- 31 + 55049 = 55080
- 59 + 55021 = 55080
- 71 + 55009 = 55080
- 79 + 55001 = 55080
Showing the first eight; more decompositions exist.
