Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535254, here are decompositions:
- 41 + 31535213 = 31535254
- 71 + 31535183 = 31535254
- 83 + 31535171 = 31535254
- 131 + 31535123 = 31535254
- 173 + 31535081 = 31535254
- 197 + 31535057 = 31535254
- 293 + 31534961 = 31535254
- 383 + 31534871 = 31535254
Showing the first eight; more decompositions exist.
