Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525480, here are decompositions:
- 3 + 31525477 = 31525480
- 59 + 31525421 = 31525480
- 83 + 31525397 = 31525480
- 101 + 31525379 = 31525480
- 113 + 31525367 = 31525480
- 137 + 31525343 = 31525480
- 149 + 31525331 = 31525480
- 191 + 31525289 = 31525480
Showing the first eight; more decompositions exist.
