Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529776, here are decompositions:
- 59 + 31529717 = 31529776
- 107 + 31529669 = 31529776
- 269 + 31529507 = 31529776
- 503 + 31529273 = 31529776
- 557 + 31529219 = 31529776
- 563 + 31529213 = 31529776
- 809 + 31528967 = 31529776
- 953 + 31528823 = 31529776
Showing the first eight; more decompositions exist.
