Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540608, here are decompositions:
- 79 + 31540529 = 31540608
- 107 + 31540501 = 31540608
- 109 + 31540499 = 31540608
- 137 + 31540471 = 31540608
- 167 + 31540441 = 31540608
- 191 + 31540417 = 31540608
- 269 + 31540339 = 31540608
- 311 + 31540297 = 31540608
Showing the first eight; more decompositions exist.
