Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147438824, here are decompositions:
- 107 + 2147438717 = 2147438824
- 137 + 2147438687 = 2147438824
- 191 + 2147438633 = 2147438824
- 383 + 2147438441 = 2147438824
- 431 + 2147438393 = 2147438824
- 467 + 2147438357 = 2147438824
- 521 + 2147438303 = 2147438824
- 563 + 2147438261 = 2147438824
Showing the first eight; more decompositions exist.
