Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387072, here are decompositions:
- 13 + 2147387059 = 2147387072
- 43 + 2147387029 = 2147387072
- 151 + 2147386921 = 2147387072
- 373 + 2147386699 = 2147387072
- 433 + 2147386639 = 2147387072
- 601 + 2147386471 = 2147387072
- 613 + 2147386459 = 2147387072
- 769 + 2147386303 = 2147387072
Showing the first eight; more decompositions exist.
