Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546040, here are decompositions:
- 139 + 31545901 = 31546040
- 181 + 31545859 = 31546040
- 199 + 31545841 = 31546040
- 277 + 31545763 = 31546040
- 373 + 31545667 = 31546040
- 433 + 31545607 = 31546040
- 541 + 31545499 = 31546040
- 571 + 31545469 = 31546040
Showing the first eight; more decompositions exist.
