Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98642, here are decompositions:
- 3 + 98639 = 98642
- 79 + 98563 = 98642
- 109 + 98533 = 98642
- 151 + 98491 = 98642
- 163 + 98479 = 98642
- 199 + 98443 = 98642
- 223 + 98419 = 98642
- 373 + 98269 = 98642
Showing the first eight; more decompositions exist.
