Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720302, here are decompositions:

113 + 8720189 = 8720302
131 + 8720171 = 8720302
191 + 8720111 = 8720302
359 + 8719943 = 8720302
599 + 8719703 = 8720302
641 + 8719661 = 8720302
761 + 8719541 = 8720302
881 + 8719421 = 8720302

Showing the first eight; more decompositions exist.
