Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387626, here are decompositions:
- 17 + 2147387609 = 2147387626
- 53 + 2147387573 = 2147387626
- 233 + 2147387393 = 2147387626
- 347 + 2147387279 = 2147387626
- 563 + 2147387063 = 2147387626
- 617 + 2147387009 = 2147387626
- 743 + 2147386883 = 2147387626
- 773 + 2147386853 = 2147387626
Showing the first eight; more decompositions exist.
