Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 366, here are decompositions:

  • 7 + 359 = 366
  • 13 + 353 = 366
  • 17 + 349 = 366
  • 19 + 347 = 366
  • 29 + 337 = 366
  • 53 + 313 = 366
  • 59 + 307 = 366
  • 73 + 293 = 366

Showing the first eight; more decompositions exist.
