Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609610, here are decompositions:

61 + 31609549 = 31609610
79 + 31609531 = 31609610
157 + 31609453 = 31609610
229 + 31609381 = 31609610
271 + 31609339 = 31609610
379 + 31609231 = 31609610
397 + 31609213 = 31609610
421 + 31609189 = 31609610

Showing the first eight; more decompositions exist.
