Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538094, here are decompositions:
- 23 + 31538071 = 31538094
- 31 + 31538063 = 31538094
- 41 + 31538053 = 31538094
- 47 + 31538047 = 31538094
- 61 + 31538033 = 31538094
- 97 + 31537997 = 31538094
- 113 + 31537981 = 31538094
- 173 + 31537921 = 31538094
Showing the first eight; more decompositions exist.
