Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546090, here are decompositions:
- 71 + 31546019 = 31546090
- 83 + 31546007 = 31546090
- 131 + 31545959 = 31546090
- 137 + 31545953 = 31546090
- 167 + 31545923 = 31546090
- 347 + 31545743 = 31546090
- 353 + 31545737 = 31546090
- 449 + 31545641 = 31546090
Showing the first eight; more decompositions exist.
