Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447104, here are decompositions:
- 5 + 31447099 = 31447104
- 23 + 31447081 = 31447104
- 61 + 31447043 = 31447104
- 83 + 31447021 = 31447104
- 103 + 31447001 = 31447104
- 107 + 31446997 = 31447104
- 131 + 31446973 = 31447104
- 151 + 31446953 = 31447104
Showing the first eight; more decompositions exist.
