Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528584, here are decompositions:
- 5 + 31528579 = 31528584
- 11 + 31528573 = 31528584
- 37 + 31528547 = 31528584
- 53 + 31528531 = 31528584
- 83 + 31528501 = 31528584
- 137 + 31528447 = 31528584
- 151 + 31528433 = 31528584
- 211 + 31528373 = 31528584
Showing the first eight; more decompositions exist.
