Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493104, here are decompositions:
- 47 + 31493057 = 31493104
- 107 + 31492997 = 31493104
- 113 + 31492991 = 31493104
- 197 + 31492907 = 31493104
- 257 + 31492847 = 31493104
- 263 + 31492841 = 31493104
- 347 + 31492757 = 31493104
- 353 + 31492751 = 31493104
Showing the first eight; more decompositions exist.
