Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738138, here are decompositions:

37 + 8738101 = 8738138
67 + 8738071 = 8738138
127 + 8738011 = 8738138
271 + 8737867 = 8738138
337 + 8737801 = 8738138
349 + 8737789 = 8738138
397 + 8737741 = 8738138
421 + 8737717 = 8738138

Showing the first eight; more decompositions exist.
