Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720092, here are decompositions:

5 + 8720087 = 8720092
11 + 8720081 = 8720092
131 + 8719961 = 8720092
149 + 8719943 = 8720092
389 + 8719703 = 8720092
431 + 8719661 = 8720092
701 + 8719391 = 8720092
743 + 8719349 = 8720092

Showing the first eight; more decompositions exist.
