Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509718, here are decompositions:
- 59 + 31509659 = 31509718
- 89 + 31509629 = 31509718
- 101 + 31509617 = 31509718
- 311 + 31509407 = 31509718
- 347 + 31509371 = 31509718
- 389 + 31509329 = 31509718
- 467 + 31509251 = 31509718
- 641 + 31509077 = 31509718
Showing the first eight; more decompositions exist.
