Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532752, here are decompositions:
- 3 + 31532749 = 31532752
- 59 + 31532693 = 31532752
- 113 + 31532639 = 31532752
- 179 + 31532573 = 31532752
- 263 + 31532489 = 31532752
- 491 + 31532261 = 31532752
- 821 + 31531931 = 31532752
- 1103 + 31531649 = 31532752
Showing the first eight; more decompositions exist.
