Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624526, here are decompositions:

19 + 31624507 = 31624526
97 + 31624429 = 31624526
103 + 31624423 = 31624526
139 + 31624387 = 31624526
163 + 31624363 = 31624526
379 + 31624147 = 31624526
397 + 31624129 = 31624526
457 + 31624069 = 31624526

Showing the first eight; more decompositions exist.
