Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31936, here are decompositions:
- 29 + 31907 = 31936
- 53 + 31883 = 31936
- 89 + 31847 = 31936
- 137 + 31799 = 31936
- 167 + 31769 = 31936
- 269 + 31667 = 31936
- 293 + 31643 = 31936
- 353 + 31583 = 31936
Showing the first eight; more decompositions exist.
