Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738142, here are decompositions:

13 + 8738129 = 8738142
19 + 8738123 = 8738142
41 + 8738101 = 8738142
53 + 8738089 = 8738142
59 + 8738083 = 8738142
71 + 8738071 = 8738142
89 + 8738053 = 8738142
109 + 8738033 = 8738142

Showing the first eight; more decompositions exist.
