Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544174, here are decompositions:
- 3 + 31544171 = 31544174
- 7 + 31544167 = 31544174
- 43 + 31544131 = 31544174
- 97 + 31544077 = 31544174
- 163 + 31544011 = 31544174
- 271 + 31543903 = 31544174
- 331 + 31543843 = 31544174
- 397 + 31543777 = 31544174
Showing the first eight; more decompositions exist.
