Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529604, here are decompositions:
- 11 + 31529593 = 31529604
- 37 + 31529567 = 31529604
- 47 + 31529557 = 31529604
- 53 + 31529551 = 31529604
- 83 + 31529521 = 31529604
- 97 + 31529507 = 31529604
- 157 + 31529447 = 31529604
- 173 + 31529431 = 31529604
Showing the first eight; more decompositions exist.
