Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543600, here are decompositions:
- 29 + 31543571 = 31543600
- 71 + 31543529 = 31543600
- 149 + 31543451 = 31543600
- 239 + 31543361 = 31543600
- 251 + 31543349 = 31543600
- 269 + 31543331 = 31543600
- 383 + 31543217 = 31543600
- 419 + 31543181 = 31543600
Showing the first eight; more decompositions exist.
