Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147448670, here are decompositions:
- 41 + 2147448629 = 2147448670
- 89 + 2147448581 = 2147448670
- 131 + 2147448539 = 2147448670
- 197 + 2147448473 = 2147448670
- 317 + 2147448353 = 2147448670
- 347 + 2147448323 = 2147448670
- 383 + 2147448287 = 2147448670
- 569 + 2147448101 = 2147448670
Showing the first eight; more decompositions exist.
