Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612378, here are decompositions:
- 71 + 31612307 = 31612378
- 101 + 31612277 = 31612378
- 137 + 31612241 = 31612378
- 179 + 31612199 = 31612378
- 227 + 31612151 = 31612378
- 257 + 31612121 = 31612378
- 269 + 31612109 = 31612378
- 461 + 31611917 = 31612378
Showing the first eight; more decompositions exist.
