Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587032, here are decompositions:
- 3 + 31587029 = 31587032
- 13 + 31587019 = 31587032
- 163 + 31586869 = 31587032
- 193 + 31586839 = 31587032
- 223 + 31586809 = 31587032
- 229 + 31586803 = 31587032
- 241 + 31586791 = 31587032
- 313 + 31586719 = 31587032
Showing the first eight; more decompositions exist.
