Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31236, here are decompositions:
- 5 + 31231 = 31236
- 13 + 31223 = 31236
- 17 + 31219 = 31236
- 43 + 31193 = 31236
- 47 + 31189 = 31236
- 53 + 31183 = 31236
- 59 + 31177 = 31236
- 83 + 31153 = 31236
Showing the first eight; more decompositions exist.
