Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525284, here are decompositions:
- 5 + 31525279 = 31525284
- 17 + 31525267 = 31525284
- 23 + 31525261 = 31525284
- 41 + 31525243 = 31525284
- 71 + 31525213 = 31525284
- 73 + 31525211 = 31525284
- 83 + 31525201 = 31525284
- 101 + 31525183 = 31525284
Showing the first eight; more decompositions exist.
