Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15492, here are decompositions:
- 19 + 15473 = 15492
- 31 + 15461 = 15492
- 41 + 15451 = 15492
- 53 + 15439 = 15492
- 79 + 15413 = 15492
- 101 + 15391 = 15492
- 109 + 15383 = 15492
- 131 + 15361 = 15492
Showing the first eight; more decompositions exist.
