Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664742, here are decompositions:

3 + 8664739 = 8664742
11 + 8664731 = 8664742
41 + 8664701 = 8664742
71 + 8664671 = 8664742
269 + 8664473 = 8664742
311 + 8664431 = 8664742
353 + 8664389 = 8664742
431 + 8664311 = 8664742

Showing the first eight; more decompositions exist.
