Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690258, here are decompositions:

37 + 8690221 = 8690258
67 + 8690191 = 8690258
139 + 8690119 = 8690258
271 + 8689987 = 8690258
277 + 8689981 = 8690258
547 + 8689711 = 8690258
571 + 8689687 = 8690258
601 + 8689657 = 8690258

Showing the first eight; more decompositions exist.
