Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546278, here are decompositions:
- 11 + 31546267 = 31546278
- 47 + 31546231 = 31546278
- 61 + 31546217 = 31546278
- 79 + 31546199 = 31546278
- 97 + 31546181 = 31546278
- 149 + 31546129 = 31546278
- 167 + 31546111 = 31546278
- 271 + 31546007 = 31546278
Showing the first eight; more decompositions exist.
