Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757142, here are decompositions:

11 + 8757131 = 8757142
29 + 8757113 = 8757142
59 + 8757083 = 8757142
83 + 8757059 = 8757142
89 + 8757053 = 8757142
101 + 8757041 = 8757142
113 + 8757029 = 8757142
179 + 8756963 = 8757142

Showing the first eight; more decompositions exist.
