Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690642, here are decompositions:

3 + 8690639 = 8690642
31 + 8690611 = 8690642
43 + 8690599 = 8690642
229 + 8690413 = 8690642
271 + 8690371 = 8690642
283 + 8690359 = 8690642
349 + 8690293 = 8690642
421 + 8690221 = 8690642

Showing the first eight; more decompositions exist.
