Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544058, here are decompositions:
- 5 + 31544053 = 31544058
- 17 + 31544041 = 31544058
- 19 + 31544039 = 31544058
- 37 + 31544021 = 31544058
- 47 + 31544011 = 31544058
- 61 + 31543997 = 31544058
- 67 + 31543991 = 31544058
- 71 + 31543987 = 31544058
Showing the first eight; more decompositions exist.
