Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690228, here are decompositions:

7 + 8690221 = 8690228
37 + 8690191 = 8690228
109 + 8690119 = 8690228
139 + 8690089 = 8690228
241 + 8689987 = 8690228
271 + 8689957 = 8690228
499 + 8689729 = 8690228
541 + 8689687 = 8690228

Showing the first eight; more decompositions exist.
