Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605734, here are decompositions:

7 + 31605727 = 31605734
37 + 31605697 = 31605734
151 + 31605583 = 31605734
157 + 31605577 = 31605734
163 + 31605571 = 31605734
373 + 31605361 = 31605734
463 + 31605271 = 31605734
487 + 31605247 = 31605734

Showing the first eight; more decompositions exist.
