Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724002, here are decompositions:

73 + 8723929 = 8724002
103 + 8723899 = 8724002
109 + 8723893 = 8724002
151 + 8723851 = 8724002
181 + 8723821 = 8724002
271 + 8723731 = 8724002
349 + 8723653 = 8724002
409 + 8723593 = 8724002

Showing the first eight; more decompositions exist.
