Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585226, here are decompositions:
- 37 + 31585189 = 31585226
- 67 + 31585159 = 31585226
- 193 + 31585033 = 31585226
- 373 + 31584853 = 31585226
- 397 + 31584829 = 31585226
- 457 + 31584769 = 31585226
- 523 + 31584703 = 31585226
- 613 + 31584613 = 31585226
Showing the first eight; more decompositions exist.
