Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542734, here are decompositions:
- 7 + 31542727 = 31542734
- 31 + 31542703 = 31542734
- 37 + 31542697 = 31542734
- 103 + 31542631 = 31542734
- 211 + 31542523 = 31542734
- 277 + 31542457 = 31542734
- 337 + 31542397 = 31542734
- 571 + 31542163 = 31542734
Showing the first eight; more decompositions exist.
