Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535098, here are decompositions:
- 17 + 31535081 = 31535098
- 41 + 31535057 = 31535098
- 137 + 31534961 = 31535098
- 227 + 31534871 = 31535098
- 311 + 31534787 = 31535098
- 347 + 31534751 = 31535098
- 359 + 31534739 = 31535098
- 389 + 31534709 = 31535098
Showing the first eight; more decompositions exist.
