Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25418, here are decompositions:

  • 7 + 25411 = 25418
  • 61 + 25357 = 25418
  • 79 + 25339 = 25418
  • 97 + 25321 = 25418
  • 109 + 25309 = 25418
  • 157 + 25261 = 25418
  • 181 + 25237 = 25418
  • 199 + 25219 = 25418

Showing the first eight; more decompositions exist.
