Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605482, here are decompositions:

43 + 31605439 = 31605482
163 + 31605319 = 31605482
211 + 31605271 = 31605482
313 + 31605169 = 31605482
373 + 31605109 = 31605482
409 + 31605073 = 31605482
463 + 31605019 = 31605482
523 + 31604959 = 31605482

Showing the first eight; more decompositions exist.
