Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761242, here are decompositions:

5 + 8761237 = 8761242
29 + 8761213 = 8761242
73 + 8761169 = 8761242
89 + 8761153 = 8761242
101 + 8761141 = 8761242
103 + 8761139 = 8761242
109 + 8761133 = 8761242
163 + 8761079 = 8761242

Showing the first eight; more decompositions exist.
