Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544938, here are decompositions:
- 59 + 31544879 = 31544938
- 167 + 31544771 = 31544938
- 179 + 31544759 = 31544938
- 281 + 31544657 = 31544938
- 521 + 31544417 = 31544938
- 641 + 31544297 = 31544938
- 839 + 31544099 = 31544938
- 881 + 31544057 = 31544938
Showing the first eight; more decompositions exist.
