Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387250, here are decompositions:
- 23 + 2147387227 = 2147387250
- 31 + 2147387219 = 2147387250
- 37 + 2147387213 = 2147387250
- 97 + 2147387153 = 2147387250
- 167 + 2147387083 = 2147387250
- 191 + 2147387059 = 2147387250
- 233 + 2147387017 = 2147387250
- 241 + 2147387009 = 2147387250
Showing the first eight; more decompositions exist.
