Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540482, here are decompositions:
- 11 + 31540471 = 31540482
- 41 + 31540441 = 31540482
- 139 + 31540343 = 31540482
- 173 + 31540309 = 31540482
- 241 + 31540241 = 31540482
- 269 + 31540213 = 31540482
- 271 + 31540211 = 31540482
- 293 + 31540189 = 31540482
Showing the first eight; more decompositions exist.
