Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528944, here are decompositions:
- 101 + 31528843 = 31528944
- 103 + 31528841 = 31528944
- 113 + 31528831 = 31528944
- 131 + 31528813 = 31528944
- 137 + 31528807 = 31528944
- 193 + 31528751 = 31528944
- 311 + 31528633 = 31528944
- 331 + 31528613 = 31528944
Showing the first eight; more decompositions exist.
