Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469228, here are decompositions:

59 + 469169 = 469228
101 + 469127 = 469228
107 + 469121 = 469228
191 + 469037 = 469228
197 + 469031 = 469228
359 + 468869 = 469228
467 + 468761 = 469228
491 + 468737 = 469228

Showing the first eight; more decompositions exist.
