Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544472, here are decompositions:
- 79 + 31544393 = 31544472
- 101 + 31544371 = 31544472
- 109 + 31544363 = 31544472
- 149 + 31544323 = 31544472
- 191 + 31544281 = 31544472
- 251 + 31544221 = 31544472
- 283 + 31544189 = 31544472
- 293 + 31544179 = 31544472
Showing the first eight; more decompositions exist.
