Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544430, here are decompositions:
- 13 + 31544417 = 31544430
- 37 + 31544393 = 31544430
- 59 + 31544371 = 31544430
- 67 + 31544363 = 31544430
- 83 + 31544347 = 31544430
- 107 + 31544323 = 31544430
- 149 + 31544281 = 31544430
- 223 + 31544207 = 31544430
Showing the first eight; more decompositions exist.
