Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467150, here are decompositions:
- 17 + 31467133 = 31467150
- 23 + 31467127 = 31467150
- 47 + 31467103 = 31467150
- 61 + 31467089 = 31467150
- 67 + 31467083 = 31467150
- 79 + 31467071 = 31467150
- 83 + 31467067 = 31467150
- 139 + 31467011 = 31467150
Showing the first eight; more decompositions exist.
