Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538112, here are decompositions:
- 5 + 31538107 = 31538112
- 41 + 31538071 = 31538112
- 59 + 31538053 = 31538112
- 79 + 31538033 = 31538112
- 83 + 31538029 = 31538112
- 113 + 31537999 = 31538112
- 131 + 31537981 = 31538112
- 173 + 31537939 = 31538112
Showing the first eight; more decompositions exist.
