Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55490, here are decompositions:
- 3 + 55487 = 55490
- 79 + 55411 = 55490
- 109 + 55381 = 55490
- 139 + 55351 = 55490
- 151 + 55339 = 55490
- 157 + 55333 = 55490
- 199 + 55291 = 55490
- 241 + 55249 = 55490
Showing the first eight; more decompositions exist.
