Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529624, here are decompositions:
- 31 + 31529593 = 31529624
- 67 + 31529557 = 31529624
- 73 + 31529551 = 31529624
- 103 + 31529521 = 31529624
- 193 + 31529431 = 31529624
- 211 + 31529413 = 31529624
- 271 + 31529353 = 31529624
- 277 + 31529347 = 31529624
Showing the first eight; more decompositions exist.
