Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626614, here are decompositions:

7 + 31626607 = 31626614
43 + 31626571 = 31626614
67 + 31626547 = 31626614
193 + 31626421 = 31626614
277 + 31626337 = 31626614
367 + 31626247 = 31626614
421 + 31626193 = 31626614
541 + 31626073 = 31626614

Showing the first eight; more decompositions exist.
