Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543548, here are decompositions:
- 5 + 31543543 = 31543548
- 17 + 31543531 = 31543548
- 19 + 31543529 = 31543548
- 59 + 31543489 = 31543548
- 67 + 31543481 = 31543548
- 97 + 31543451 = 31543548
- 151 + 31543397 = 31543548
- 199 + 31543349 = 31543548
Showing the first eight; more decompositions exist.
