Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504888, here are decompositions:
- 5 + 31504883 = 31504888
- 89 + 31504799 = 31504888
- 197 + 31504691 = 31504888
- 227 + 31504661 = 31504888
- 269 + 31504619 = 31504888
- 281 + 31504607 = 31504888
- 449 + 31504439 = 31504888
- 521 + 31504367 = 31504888
Showing the first eight; more decompositions exist.
