Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45278, here are decompositions:
- 19 + 45259 = 45278
- 31 + 45247 = 45278
- 97 + 45181 = 45278
- 139 + 45139 = 45278
- 151 + 45127 = 45278
- 157 + 45121 = 45278
- 271 + 45007 = 45278
- 307 + 44971 = 45278
Showing the first eight; more decompositions exist.
