Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546140, here are decompositions:
- 11 + 31546129 = 31546140
- 29 + 31546111 = 31546140
- 71 + 31546069 = 31546140
- 127 + 31546013 = 31546140
- 149 + 31545991 = 31546140
- 181 + 31545959 = 31546140
- 239 + 31545901 = 31546140
- 281 + 31545859 = 31546140
Showing the first eight; more decompositions exist.
