Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546188, here are decompositions:
- 7 + 31546181 = 31546188
- 29 + 31546159 = 31546188
- 59 + 31546129 = 31546188
- 181 + 31546007 = 31546188
- 197 + 31545991 = 31546188
- 229 + 31545959 = 31546188
- 269 + 31545919 = 31546188
- 347 + 31545841 = 31546188
Showing the first eight; more decompositions exist.
