Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546142, here are decompositions:
- 13 + 31546129 = 31546142
- 31 + 31546111 = 31546142
- 73 + 31546069 = 31546142
- 79 + 31546063 = 31546142
- 151 + 31545991 = 31546142
- 223 + 31545919 = 31546142
- 241 + 31545901 = 31546142
- 283 + 31545859 = 31546142
Showing the first eight; more decompositions exist.
