Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447094, here are decompositions:
- 13 + 31447081 = 31447094
- 67 + 31447027 = 31447094
- 73 + 31447021 = 31447094
- 97 + 31446997 = 31447094
- 157 + 31446937 = 31447094
- 223 + 31446871 = 31447094
- 241 + 31446853 = 31447094
- 337 + 31446757 = 31447094
Showing the first eight; more decompositions exist.
