Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536472, here are decompositions:
- 89 + 31536383 = 31536472
- 113 + 31536359 = 31536472
- 179 + 31536293 = 31536472
- 269 + 31536203 = 31536472
- 311 + 31536161 = 31536472
- 419 + 31536053 = 31536472
- 491 + 31535981 = 31536472
- 563 + 31535909 = 31536472
Showing the first eight; more decompositions exist.
