Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527936, here are decompositions:
- 5 + 31527931 = 31527936
- 23 + 31527913 = 31527936
- 107 + 31527829 = 31527936
- 109 + 31527827 = 31527936
- 149 + 31527787 = 31527936
- 227 + 31527709 = 31527936
- 233 + 31527703 = 31527936
- 239 + 31527697 = 31527936
Showing the first eight; more decompositions exist.
