Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546158, here are decompositions:
- 5 + 31546153 = 31546158
- 29 + 31546129 = 31546158
- 47 + 31546111 = 31546158
- 89 + 31546069 = 31546158
- 139 + 31546019 = 31546158
- 151 + 31546007 = 31546158
- 167 + 31545991 = 31546158
- 199 + 31545959 = 31546158
Showing the first eight; more decompositions exist.
