Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548992, here are decompositions:
- 31 + 31548961 = 31548992
- 229 + 31548763 = 31548992
- 373 + 31548619 = 31548992
- 379 + 31548613 = 31548992
- 661 + 31548331 = 31548992
- 691 + 31548301 = 31548992
- 859 + 31548133 = 31548992
- 883 + 31548109 = 31548992
Showing the first eight; more decompositions exist.
