Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709912, here are decompositions:

41 + 8709871 = 8709912
73 + 8709839 = 8709912
131 + 8709781 = 8709912
181 + 8709731 = 8709912
191 + 8709721 = 8709912
193 + 8709719 = 8709912
199 + 8709713 = 8709912
349 + 8709563 = 8709912

Showing the first eight; more decompositions exist.
