Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624466, here are decompositions:

37 + 31624429 = 31624466
43 + 31624423 = 31624466
79 + 31624387 = 31624466
103 + 31624363 = 31624466
109 + 31624357 = 31624466
127 + 31624339 = 31624466
337 + 31624129 = 31624466
397 + 31624069 = 31624466

Showing the first eight; more decompositions exist.
