Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731182, here are decompositions:

29 + 8731153 = 8731182
41 + 8731141 = 8731182
43 + 8731139 = 8731182
71 + 8731111 = 8731182
73 + 8731109 = 8731182
79 + 8731103 = 8731182
113 + 8731069 = 8731182
151 + 8731031 = 8731182

Showing the first eight; more decompositions exist.
