Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131698, here are decompositions:
- 11 + 131687 = 131698
- 59 + 131639 = 131698
- 71 + 131627 = 131698
- 107 + 131591 = 131698
- 137 + 131561 = 131698
- 179 + 131519 = 131698
- 191 + 131507 = 131698
- 197 + 131501 = 131698
Showing the first eight; more decompositions exist.
