Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606010, here are decompositions:

97 + 31605913 = 31606010
199 + 31605811 = 31606010
229 + 31605781 = 31606010
283 + 31605727 = 31606010
313 + 31605697 = 31606010
433 + 31605577 = 31606010
439 + 31605571 = 31606010
571 + 31605439 = 31606010

Showing the first eight; more decompositions exist.
