Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707072, here are decompositions:

41 + 8707031 = 8707072
89 + 8706983 = 8707072
191 + 8706881 = 8707072
239 + 8706833 = 8707072
281 + 8706791 = 8707072
401 + 8706671 = 8707072
461 + 8706611 = 8707072
503 + 8706569 = 8707072

Showing the first eight; more decompositions exist.
