Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131740, here are decompositions:
- 29 + 131711 = 131740
- 53 + 131687 = 131740
- 101 + 131639 = 131740
- 113 + 131627 = 131740
- 149 + 131591 = 131740
- 179 + 131561 = 131740
- 197 + 131543 = 131740
- 233 + 131507 = 131740
Showing the first eight; more decompositions exist.
