Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720052, here are decompositions:

53 + 8719999 = 8720052
101 + 8719951 = 8720052
109 + 8719943 = 8720052
113 + 8719939 = 8720052
149 + 8719903 = 8720052
179 + 8719873 = 8720052
233 + 8719819 = 8720052
239 + 8719813 = 8720052

Showing the first eight; more decompositions exist.
