Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742584, here are decompositions:

7 + 8742577 = 8742584
13 + 8742571 = 8742584
43 + 8742541 = 8742584
73 + 8742511 = 8742584
163 + 8742421 = 8742584
271 + 8742313 = 8742584
397 + 8742187 = 8742584
463 + 8742121 = 8742584

Showing the first eight; more decompositions exist.
