Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528872, here are decompositions:
- 19 + 31528853 = 31528872
- 29 + 31528843 = 31528872
- 31 + 31528841 = 31528872
- 41 + 31528831 = 31528872
- 59 + 31528813 = 31528872
- 61 + 31528811 = 31528872
- 71 + 31528801 = 31528872
- 131 + 31528741 = 31528872
Showing the first eight; more decompositions exist.
