Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142948, here are decompositions:

  • 41 + 142907 = 142948
  • 107 + 142841 = 142948
  • 137 + 142811 = 142948
  • 149 + 142799 = 142948
  • 191 + 142757 = 142948
  • 251 + 142697 = 142948
  • 347 + 142601 = 142948
  • 359 + 142589 = 142948

Showing the first eight; more decompositions exist.
