Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498632, here are decompositions:
- 41 + 31498591 = 31498632
- 73 + 31498559 = 31498632
- 83 + 31498549 = 31498632
- 103 + 31498529 = 31498632
- 163 + 31498469 = 31498632
- 211 + 31498421 = 31498632
- 283 + 31498349 = 31498632
- 353 + 31498279 = 31498632
Showing the first eight; more decompositions exist.
