Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467408, here are decompositions:
- 19 + 31467389 = 31467408
- 41 + 31467367 = 31467408
- 61 + 31467347 = 31467408
- 79 + 31467329 = 31467408
- 97 + 31467311 = 31467408
- 107 + 31467301 = 31467408
- 149 + 31467259 = 31467408
- 157 + 31467251 = 31467408
Showing the first eight; more decompositions exist.
