Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546212, here are decompositions:
- 13 + 31546199 = 31546212
- 31 + 31546181 = 31546212
- 53 + 31546159 = 31546212
- 59 + 31546153 = 31546212
- 83 + 31546129 = 31546212
- 101 + 31546111 = 31546212
- 149 + 31546063 = 31546212
- 193 + 31546019 = 31546212
Showing the first eight; more decompositions exist.
