Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147376628, here are decompositions:
- 11 + 2147376617 = 2147376628
- 71 + 2147376557 = 2147376628
- 227 + 2147376401 = 2147376628
- 251 + 2147376377 = 2147376628
- 479 + 2147376149 = 2147376628
- 569 + 2147376059 = 2147376628
- 641 + 2147375987 = 2147376628
- 659 + 2147375969 = 2147376628
Showing the first eight; more decompositions exist.
