Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387070, here are decompositions:
- 7 + 2147387063 = 2147387070
- 11 + 2147387059 = 2147387070
- 41 + 2147387029 = 2147387070
- 53 + 2147387017 = 2147387070
- 61 + 2147387009 = 2147387070
- 67 + 2147387003 = 2147387070
- 83 + 2147386987 = 2147387070
- 149 + 2147386921 = 2147387070
Showing the first eight; more decompositions exist.
