Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529034, here are decompositions:
- 37 + 31528997 = 31529034
- 41 + 31528993 = 31529034
- 67 + 31528967 = 31529034
- 181 + 31528853 = 31529034
- 191 + 31528843 = 31529034
- 193 + 31528841 = 31529034
- 211 + 31528823 = 31529034
- 223 + 31528811 = 31529034
Showing the first eight; more decompositions exist.
