Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547648, here are decompositions:
- 7 + 31547641 = 31547648
- 19 + 31547629 = 31547648
- 31 + 31547617 = 31547648
- 109 + 31547539 = 31547648
- 199 + 31547449 = 31547648
- 331 + 31547317 = 31547648
- 367 + 31547281 = 31547648
- 439 + 31547209 = 31547648
Showing the first eight; more decompositions exist.
