Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541304, here are decompositions:
- 7 + 31541297 = 31541304
- 23 + 31541281 = 31541304
- 37 + 31541267 = 31541304
- 61 + 31541243 = 31541304
- 71 + 31541233 = 31541304
- 131 + 31541173 = 31541304
- 163 + 31541141 = 31541304
- 191 + 31541113 = 31541304
Showing the first eight; more decompositions exist.
