Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532570, here are decompositions:
- 19 + 31532551 = 31532570
- 31 + 31532539 = 31532570
- 73 + 31532497 = 31532570
- 229 + 31532341 = 31532570
- 241 + 31532329 = 31532570
- 367 + 31532203 = 31532570
- 457 + 31532113 = 31532570
- 499 + 31532071 = 31532570
Showing the first eight; more decompositions exist.
