Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543576, here are decompositions:
- 5 + 31543571 = 31543576
- 47 + 31543529 = 31543576
- 179 + 31543397 = 31543576
- 227 + 31543349 = 31543576
- 353 + 31543223 = 31543576
- 359 + 31543217 = 31543576
- 443 + 31543133 = 31543576
- 509 + 31543067 = 31543576
Showing the first eight; more decompositions exist.
