Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526750, here are decompositions:
- 19 + 31526731 = 31526750
- 37 + 31526713 = 31526750
- 61 + 31526689 = 31526750
- 103 + 31526647 = 31526750
- 223 + 31526527 = 31526750
- 331 + 31526419 = 31526750
- 379 + 31526371 = 31526750
- 433 + 31526317 = 31526750
Showing the first eight; more decompositions exist.
