Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147437294, here are decompositions:
- 3 + 2147437291 = 2147437294
- 11 + 2147437283 = 2147437294
- 113 + 2147437181 = 2147437294
- 293 + 2147437001 = 2147437294
- 461 + 2147436833 = 2147437294
- 593 + 2147436701 = 2147437294
- 683 + 2147436611 = 2147437294
- 941 + 2147436353 = 2147437294
Showing the first eight; more decompositions exist.
