Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732740, here are decompositions:

53 + 8732687 = 8732740
101 + 8732639 = 8732740
113 + 8732627 = 8732740
167 + 8732573 = 8732740
239 + 8732501 = 8732740
251 + 8732489 = 8732740
293 + 8732447 = 8732740
311 + 8732429 = 8732740

Showing the first eight; more decompositions exist.
