Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147423848, here are decompositions:
- 131 + 2147423717 = 2147423848
- 137 + 2147423711 = 2147423848
- 197 + 2147423651 = 2147423848
- 359 + 2147423489 = 2147423848
- 599 + 2147423249 = 2147423848
- 659 + 2147423189 = 2147423848
- 761 + 2147423087 = 2147423848
- 821 + 2147423027 = 2147423848
Showing the first eight; more decompositions exist.
