Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505594, here are decompositions:

61 + 31505533 = 31505594
67 + 31505527 = 31505594
73 + 31505521 = 31505594
151 + 31505443 = 31505594
163 + 31505431 = 31505594
223 + 31505371 = 31505594
457 + 31505137 = 31505594
607 + 31504987 = 31505594

Showing the first eight; more decompositions exist.
