Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567476, here are decompositions:
- 47 + 31567429 = 31567476
- 79 + 31567397 = 31567476
- 107 + 31567369 = 31567476
- 163 + 31567313 = 31567476
- 179 + 31567297 = 31567476
- 197 + 31567279 = 31567476
- 257 + 31567219 = 31567476
- 263 + 31567213 = 31567476
Showing the first eight; more decompositions exist.
