Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730722, here are decompositions:

31 + 8730691 = 8730722
61 + 8730661 = 8730722
73 + 8730649 = 8730722
103 + 8730619 = 8730722
139 + 8730583 = 8730722
163 + 8730559 = 8730722
193 + 8730529 = 8730722
211 + 8730511 = 8730722

Showing the first eight; more decompositions exist.
