Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131548, here are decompositions:
- 5 + 131543 = 131548
- 29 + 131519 = 131548
- 41 + 131507 = 131548
- 47 + 131501 = 131548
- 59 + 131489 = 131548
- 71 + 131477 = 131548
- 101 + 131447 = 131548
- 107 + 131441 = 131548
Showing the first eight; more decompositions exist.
