Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719974, here are decompositions:

13 + 8719961 = 8719974
23 + 8719951 = 8719974
31 + 8719943 = 8719974
71 + 8719903 = 8719974
101 + 8719873 = 8719974
127 + 8719847 = 8719974
157 + 8719817 = 8719974
173 + 8719801 = 8719974

Showing the first eight; more decompositions exist.
