Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595928, here are decompositions:
- 47 + 31595881 = 31595928
- 59 + 31595869 = 31595928
- 61 + 31595867 = 31595928
- 97 + 31595831 = 31595928
- 151 + 31595777 = 31595928
- 157 + 31595771 = 31595928
- 197 + 31595731 = 31595928
- 211 + 31595717 = 31595928
Showing the first eight; more decompositions exist.
