Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29578, here are decompositions:

  • 5 + 29573 = 29578
  • 11 + 29567 = 29578
  • 41 + 29537 = 29578
  • 47 + 29531 = 29578
  • 149 + 29429 = 29578
  • 167 + 29411 = 29578
  • 179 + 29399 = 29578
  • 191 + 29387 = 29578

Showing the first eight; more decompositions exist.
