Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618750, here are decompositions:
- 47 + 31618703 = 31618750
- 113 + 31618637 = 31618750
- 347 + 31618403 = 31618750
- 389 + 31618361 = 31618750
- 431 + 31618319 = 31618750
- 461 + 31618289 = 31618750
- 557 + 31618193 = 31618750
- 563 + 31618187 = 31618750
Showing the first eight; more decompositions exist.
