Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422012, here are decompositions:
- 23 + 2147421989 = 2147422012
- 59 + 2147421953 = 2147422012
- 101 + 2147421911 = 2147422012
- 179 + 2147421833 = 2147422012
- 419 + 2147421593 = 2147422012
- 431 + 2147421581 = 2147422012
- 563 + 2147421449 = 2147422012
- 683 + 2147421329 = 2147422012
Showing the first eight; more decompositions exist.
