Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532648, here are decompositions:
- 61 + 31532587 = 31532648
- 67 + 31532581 = 31532648
- 97 + 31532551 = 31532648
- 109 + 31532539 = 31532648
- 127 + 31532521 = 31532648
- 151 + 31532497 = 31532648
- 211 + 31532437 = 31532648
- 307 + 31532341 = 31532648
Showing the first eight; more decompositions exist.
