Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535532, here are decompositions:
- 29 + 31535503 = 31535532
- 103 + 31535429 = 31535532
- 109 + 31535423 = 31535532
- 113 + 31535419 = 31535532
- 151 + 31535381 = 31535532
- 191 + 31535341 = 31535532
- 211 + 31535321 = 31535532
- 269 + 31535263 = 31535532
Showing the first eight; more decompositions exist.
