Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387746, here are decompositions:
- 3 + 2147387743 = 2147387746
- 5 + 2147387741 = 2147387746
- 17 + 2147387729 = 2147387746
- 47 + 2147387699 = 2147387746
- 137 + 2147387609 = 2147387746
- 173 + 2147387573 = 2147387746
- 239 + 2147387507 = 2147387746
- 353 + 2147387393 = 2147387746
Showing the first eight; more decompositions exist.
