Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589072, here are decompositions:
- 3 + 31589069 = 31589072
- 61 + 31589011 = 31589072
- 79 + 31588993 = 31589072
- 139 + 31588933 = 31589072
- 373 + 31588699 = 31589072
- 379 + 31588693 = 31589072
- 601 + 31588471 = 31589072
- 631 + 31588441 = 31589072
Showing the first eight; more decompositions exist.
