Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562870, here are decompositions:
- 43 + 31562827 = 31562870
- 103 + 31562767 = 31562870
- 193 + 31562677 = 31562870
- 277 + 31562593 = 31562870
- 421 + 31562449 = 31562870
- 439 + 31562431 = 31562870
- 523 + 31562347 = 31562870
- 541 + 31562329 = 31562870
Showing the first eight; more decompositions exist.
