Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147573874, here are decompositions:
- 13 + 2147573861 = 2147573874
- 23 + 2147573851 = 2147573874
- 31 + 2147573843 = 2147573874
- 113 + 2147573761 = 2147573874
- 211 + 2147573663 = 2147573874
- 223 + 2147573651 = 2147573874
- 263 + 2147573611 = 2147573874
- 331 + 2147573543 = 2147573874
Showing the first eight; more decompositions exist.
