Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481450, here are decompositions:
- 19 + 31481431 = 31481450
- 31 + 31481419 = 31481450
- 43 + 31481407 = 31481450
- 61 + 31481389 = 31481450
- 67 + 31481383 = 31481450
- 79 + 31481371 = 31481450
- 97 + 31481353 = 31481450
- 109 + 31481341 = 31481450
Showing the first eight; more decompositions exist.
