Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525494, here are decompositions:
- 5 + 31525489 = 31525494
- 17 + 31525477 = 31525494
- 47 + 31525447 = 31525494
- 73 + 31525421 = 31525494
- 97 + 31525397 = 31525494
- 127 + 31525367 = 31525494
- 151 + 31525343 = 31525494
- 163 + 31525331 = 31525494
Showing the first eight; more decompositions exist.
