Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532120, here are decompositions:
- 3 + 31532117 = 31532120
- 7 + 31532113 = 31532120
- 31 + 31532089 = 31532120
- 199 + 31531921 = 31532120
- 211 + 31531909 = 31532120
- 307 + 31531813 = 31532120
- 541 + 31531579 = 31532120
- 751 + 31531369 = 31532120
Showing the first eight; more decompositions exist.
