Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612408, here are decompositions:
- 17 + 31612391 = 31612408
- 101 + 31612307 = 31612408
- 131 + 31612277 = 31612408
- 167 + 31612241 = 31612408
- 257 + 31612151 = 31612408
- 467 + 31611941 = 31612408
- 491 + 31611917 = 31612408
- 557 + 31611851 = 31612408
Showing the first eight; more decompositions exist.
