Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547044, here are decompositions:
- 5 + 31547039 = 31547044
- 41 + 31547003 = 31547044
- 47 + 31546997 = 31547044
- 107 + 31546937 = 31547044
- 131 + 31546913 = 31547044
- 197 + 31546847 = 31547044
- 227 + 31546817 = 31547044
- 383 + 31546661 = 31547044
Showing the first eight; more decompositions exist.
