Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744280, here are decompositions:

  • 11 + 8744269 = 8744280
  • 19 + 8744261 = 8744280
  • 37 + 8744243 = 8744280
  • 47 + 8744233 = 8744280
  • 53 + 8744227 = 8744280
  • 73 + 8744207 = 8744280
  • 89 + 8744191 = 8744280
  • 131 + 8744149 = 8744280

Showing the first eight; more decompositions exist.
