Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626590, here are decompositions:

19 + 31626571 = 31626590
43 + 31626547 = 31626590
97 + 31626493 = 31626590
109 + 31626481 = 31626590
223 + 31626367 = 31626590
397 + 31626193 = 31626590
571 + 31626019 = 31626590
673 + 31625917 = 31626590

Showing the first eight; more decompositions exist.
