Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547434, here are decompositions:
- 131 + 31547303 = 31547434
- 137 + 31547297 = 31547434
- 167 + 31547267 = 31547434
- 173 + 31547261 = 31547434
- 257 + 31547177 = 31547434
- 431 + 31547003 = 31547434
- 521 + 31546913 = 31547434
- 587 + 31546847 = 31547434
Showing the first eight; more decompositions exist.
