Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489262, here are decompositions:
- 19 + 2147489243 = 2147489262
- 59 + 2147489203 = 2147489262
- 173 + 2147489089 = 2147489262
- 179 + 2147489083 = 2147489262
- 239 + 2147489023 = 2147489262
- 349 + 2147488913 = 2147489262
- 521 + 2147488741 = 2147489262
- 571 + 2147488691 = 2147489262
Showing the first eight; more decompositions exist.
