Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744142, here are decompositions:

13 + 8744129 = 8744142
41 + 8744101 = 8744142
59 + 8744083 = 8744142
61 + 8744081 = 8744142
79 + 8744063 = 8744142
101 + 8744041 = 8744142
109 + 8744033 = 8744142
139 + 8744003 = 8744142

Showing the first eight; more decompositions exist.
