Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470138, here are decompositions:

7 + 470131 = 470138
61 + 470077 = 470138
79 + 470059 = 470138
181 + 469957 = 470138
199 + 469939 = 470138
337 + 469801 = 470138
421 + 469717 = 470138
577 + 469561 = 470138

Showing the first eight; more decompositions exist.
