Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498616, here are decompositions:
- 67 + 31498549 = 31498616
- 103 + 31498513 = 31498616
- 337 + 31498279 = 31498616
- 547 + 31498069 = 31498616
- 577 + 31498039 = 31498616
- 607 + 31498009 = 31498616
- 613 + 31498003 = 31498616
- 619 + 31497997 = 31498616
Showing the first eight; more decompositions exist.
