Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532350, here are decompositions:
- 11 + 31532339 = 31532350
- 71 + 31532279 = 31532350
- 89 + 31532261 = 31532350
- 131 + 31532219 = 31532350
- 233 + 31532117 = 31532350
- 347 + 31532003 = 31532350
- 383 + 31531967 = 31532350
- 419 + 31531931 = 31532350
Showing the first eight; more decompositions exist.
