Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720132, here are decompositions:

13 + 8720119 = 8720132
19 + 8720113 = 8720132
61 + 8720071 = 8720132
181 + 8719951 = 8720132
193 + 8719939 = 8720132
229 + 8719903 = 8720132
313 + 8719819 = 8720132
331 + 8719801 = 8720132

Showing the first eight; more decompositions exist.
