Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452626, here are decompositions:

3 + 31452623 = 31452626
19 + 31452607 = 31452626
43 + 31452583 = 31452626
97 + 31452529 = 31452626
109 + 31452517 = 31452626
547 + 31452079 = 31452626
607 + 31452019 = 31452626
613 + 31452013 = 31452626

Showing the first eight; more decompositions exist.
