Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547070, here are decompositions:
- 7 + 31547063 = 31547070
- 31 + 31547039 = 31547070
- 67 + 31547003 = 31547070
- 73 + 31546997 = 31547070
- 83 + 31546987 = 31547070
- 89 + 31546981 = 31547070
- 101 + 31546969 = 31547070
- 157 + 31546913 = 31547070
Showing the first eight; more decompositions exist.
