Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387348, here are decompositions:
- 331 + 2147387017 = 2147387348
- 619 + 2147386729 = 2147387348
- 661 + 2147386687 = 2147387348
- 709 + 2147386639 = 2147387348
- 787 + 2147386561 = 2147387348
- 877 + 2147386471 = 2147387348
- 1201 + 2147386147 = 2147387348
- 1231 + 2147386117 = 2147387348
Showing the first eight; more decompositions exist.
