Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543524, here are decompositions:
- 43 + 31543481 = 31543524
- 71 + 31543453 = 31543524
- 73 + 31543451 = 31543524
- 127 + 31543397 = 31543524
- 163 + 31543361 = 31543524
- 193 + 31543331 = 31543524
- 223 + 31543301 = 31543524
- 251 + 31543273 = 31543524
Showing the first eight; more decompositions exist.
