Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61628, here are decompositions:
- 19 + 61609 = 61628
- 67 + 61561 = 61628
- 109 + 61519 = 61628
- 157 + 61471 = 61628
- 211 + 61417 = 61628
- 271 + 61357 = 61628
- 331 + 61297 = 61628
- 337 + 61291 = 61628
Showing the first eight; more decompositions exist.
