Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702972, here are decompositions:

13 + 8702959 = 8702972
139 + 8702833 = 8702972
151 + 8702821 = 8702972
241 + 8702731 = 8702972
283 + 8702689 = 8702972
379 + 8702593 = 8702972
433 + 8702539 = 8702972
541 + 8702431 = 8702972

Showing the first eight; more decompositions exist.
