Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523800, here are decompositions:
- 47 + 31523753 = 31523800
- 131 + 31523669 = 31523800
- 149 + 31523651 = 31523800
- 167 + 31523633 = 31523800
- 263 + 31523537 = 31523800
- 359 + 31523441 = 31523800
- 389 + 31523411 = 31523800
- 401 + 31523399 = 31523800
Showing the first eight; more decompositions exist.
