Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543800, here are decompositions:
- 17 + 31543783 = 31543800
- 23 + 31543777 = 31543800
- 31 + 31543769 = 31543800
- 37 + 31543763 = 31543800
- 89 + 31543711 = 31543800
- 103 + 31543697 = 31543800
- 109 + 31543691 = 31543800
- 131 + 31543669 = 31543800
Showing the first eight; more decompositions exist.
