Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523590, here are decompositions:
- 11 + 31523579 = 31523590
- 53 + 31523537 = 31523590
- 113 + 31523477 = 31523590
- 149 + 31523441 = 31523590
- 179 + 31523411 = 31523590
- 191 + 31523399 = 31523590
- 281 + 31523309 = 31523590
- 311 + 31523279 = 31523590
Showing the first eight; more decompositions exist.
