Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658042, here are decompositions:

59 + 8657983 = 8658042
73 + 8657969 = 8658042
109 + 8657933 = 8658042
139 + 8657903 = 8658042
191 + 8657851 = 8658042
193 + 8657849 = 8658042
241 + 8657801 = 8658042
271 + 8657771 = 8658042

Showing the first eight; more decompositions exist.
