Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538848, here are decompositions:
- 41 + 31538807 = 31538848
- 59 + 31538789 = 31538848
- 137 + 31538711 = 31538848
- 269 + 31538579 = 31538848
- 359 + 31538489 = 31538848
- 521 + 31538327 = 31538848
- 587 + 31538261 = 31538848
- 641 + 31538207 = 31538848
Showing the first eight; more decompositions exist.
