Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532870, here are decompositions:
- 3 + 31532867 = 31532870
- 7 + 31532863 = 31532870
- 37 + 31532833 = 31532870
- 211 + 31532659 = 31532870
- 277 + 31532593 = 31532870
- 283 + 31532587 = 31532870
- 331 + 31532539 = 31532870
- 349 + 31532521 = 31532870
Showing the first eight; more decompositions exist.
