Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595256, here are decompositions:
- 5 + 31595251 = 31595256
- 13 + 31595243 = 31595256
- 19 + 31595237 = 31595256
- 37 + 31595219 = 31595256
- 47 + 31595209 = 31595256
- 67 + 31595189 = 31595256
- 79 + 31595177 = 31595256
- 83 + 31595173 = 31595256
Showing the first eight; more decompositions exist.
