Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742902, here are decompositions:

163 + 8742739 = 8742902
229 + 8742673 = 8742902
331 + 8742571 = 8742902
373 + 8742529 = 8742902
409 + 8742493 = 8742902
433 + 8742469 = 8742902
439 + 8742463 = 8742902
523 + 8742379 = 8742902

Showing the first eight; more decompositions exist.
