Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690740, here are decompositions:

101 + 8690639 = 8690740
137 + 8690603 = 8690740
173 + 8690567 = 8690740
251 + 8690489 = 8690740
263 + 8690477 = 8690740
353 + 8690387 = 8690740
389 + 8690351 = 8690740
449 + 8690291 = 8690740

Showing the first eight; more decompositions exist.
