Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543288, here are decompositions:
- 71 + 31543217 = 31543288
- 107 + 31543181 = 31543288
- 269 + 31543019 = 31543288
- 317 + 31542971 = 31543288
- 347 + 31542941 = 31543288
- 431 + 31542857 = 31543288
- 461 + 31542827 = 31543288
- 479 + 31542809 = 31543288
Showing the first eight; more decompositions exist.
