Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742262, here are decompositions:

3 + 8742259 = 8742262
101 + 8742161 = 8742262
251 + 8742011 = 8742262
311 + 8741951 = 8742262
401 + 8741861 = 8742262
449 + 8741813 = 8742262
461 + 8741801 = 8742262
509 + 8741753 = 8742262

Showing the first eight; more decompositions exist.
