Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724038, here are decompositions:

61 + 8723977 = 8724038
109 + 8723929 = 8724038
139 + 8723899 = 8724038
151 + 8723887 = 8724038
307 + 8723731 = 8724038
331 + 8723707 = 8724038
487 + 8723551 = 8724038
541 + 8723497 = 8724038

Showing the first eight; more decompositions exist.
