Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546100, here are decompositions:
- 31 + 31546069 = 31546100
- 37 + 31546063 = 31546100
- 109 + 31545991 = 31546100
- 181 + 31545919 = 31546100
- 199 + 31545901 = 31546100
- 241 + 31545859 = 31546100
- 337 + 31545763 = 31546100
- 433 + 31545667 = 31546100
Showing the first eight; more decompositions exist.
