Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535820, here are decompositions:
- 11 + 31535809 = 31535820
- 23 + 31535797 = 31535820
- 67 + 31535753 = 31535820
- 73 + 31535747 = 31535820
- 79 + 31535741 = 31535820
- 103 + 31535717 = 31535820
- 139 + 31535681 = 31535820
- 149 + 31535671 = 31535820
Showing the first eight; more decompositions exist.
