Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661602, here are decompositions:

31 + 8661571 = 8661602
73 + 8661529 = 8661602
163 + 8661439 = 8661602
349 + 8661253 = 8661602
379 + 8661223 = 8661602
409 + 8661193 = 8661602
421 + 8661181 = 8661602
541 + 8661061 = 8661602

Showing the first eight; more decompositions exist.
