Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732972, here are decompositions:

103 + 8732869 = 8732972
139 + 8732833 = 8732972
223 + 8732749 = 8732972
229 + 8732743 = 8732972
331 + 8732641 = 8732972
373 + 8732599 = 8732972
379 + 8732593 = 8732972
421 + 8732551 = 8732972

Showing the first eight; more decompositions exist.
