Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612474, here are decompositions:
- 83 + 31612391 = 31612474
- 167 + 31612307 = 31612474
- 197 + 31612277 = 31612474
- 233 + 31612241 = 31612474
- 251 + 31612223 = 31612474
- 353 + 31612121 = 31612474
- 431 + 31612043 = 31612474
- 461 + 31612013 = 31612474
Showing the first eight; more decompositions exist.
