Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588752, here are decompositions:
- 43 + 31588709 = 31588752
- 53 + 31588699 = 31588752
- 59 + 31588693 = 31588752
- 73 + 31588679 = 31588752
- 79 + 31588673 = 31588752
- 109 + 31588643 = 31588752
- 149 + 31588603 = 31588752
- 191 + 31588561 = 31588752
Showing the first eight; more decompositions exist.
