Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742570, here are decompositions:

19 + 8742551 = 8742570
29 + 8742541 = 8742570
41 + 8742529 = 8742570
59 + 8742511 = 8742570
71 + 8742499 = 8742570
73 + 8742497 = 8742570
101 + 8742469 = 8742570
107 + 8742463 = 8742570

Showing the first eight; more decompositions exist.
