Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730972, here are decompositions:

23 + 8730949 = 8730972
43 + 8730929 = 8730972
53 + 8730919 = 8730972
59 + 8730913 = 8730972
71 + 8730901 = 8730972
79 + 8730893 = 8730972
83 + 8730889 = 8730972
109 + 8730863 = 8730972

Showing the first eight; more decompositions exist.
