Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689972, here are decompositions:

3 + 8689969 = 8689972
23 + 8689949 = 8689972
29 + 8689943 = 8689972
131 + 8689841 = 8689972
149 + 8689823 = 8689972
173 + 8689799 = 8689972
311 + 8689661 = 8689972
419 + 8689553 = 8689972

Showing the first eight; more decompositions exist.
