Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467542, here are decompositions:
- 3 + 31467539 = 31467542
- 61 + 31467481 = 31467542
- 109 + 31467433 = 31467542
- 241 + 31467301 = 31467542
- 283 + 31467259 = 31467542
- 313 + 31467229 = 31467542
- 373 + 31467169 = 31467542
- 409 + 31467133 = 31467542
Showing the first eight; more decompositions exist.
