Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586100, here are decompositions:
- 23 + 31586077 = 31586100
- 41 + 31586059 = 31586100
- 43 + 31586057 = 31586100
- 47 + 31586053 = 31586100
- 97 + 31586003 = 31586100
- 103 + 31585997 = 31586100
- 127 + 31585973 = 31586100
- 137 + 31585963 = 31586100
Showing the first eight; more decompositions exist.
