Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45518, here are decompositions:
- 37 + 45481 = 45518
- 79 + 45439 = 45518
- 157 + 45361 = 45518
- 181 + 45337 = 45518
- 199 + 45319 = 45518
- 211 + 45307 = 45518
- 229 + 45289 = 45518
- 271 + 45247 = 45518
Showing the first eight; more decompositions exist.
