Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544044, here are decompositions:
- 3 + 31544041 = 31544044
- 5 + 31544039 = 31544044
- 11 + 31544033 = 31544044
- 23 + 31544021 = 31544044
- 47 + 31543997 = 31544044
- 53 + 31543991 = 31544044
- 83 + 31543961 = 31544044
- 131 + 31543913 = 31544044
Showing the first eight; more decompositions exist.
