Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541496, here are decompositions:
- 13 + 31541483 = 31541496
- 29 + 31541467 = 31541496
- 47 + 31541449 = 31541496
- 59 + 31541437 = 31541496
- 67 + 31541429 = 31541496
- 79 + 31541417 = 31541496
- 97 + 31541399 = 31541496
- 137 + 31541359 = 31541496
Showing the first eight; more decompositions exist.
