Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532640, here are decompositions:
- 43 + 31532597 = 31532640
- 47 + 31532593 = 31532640
- 53 + 31532587 = 31532640
- 59 + 31532581 = 31532640
- 67 + 31532573 = 31532640
- 89 + 31532551 = 31532640
- 101 + 31532539 = 31532640
- 151 + 31532489 = 31532640
Showing the first eight; more decompositions exist.
