Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626854, here are decompositions:

13 + 31626841 = 31626854
67 + 31626787 = 31626854
163 + 31626691 = 31626854
283 + 31626571 = 31626854
307 + 31626547 = 31626854
373 + 31626481 = 31626854
433 + 31626421 = 31626854
487 + 31626367 = 31626854

Showing the first eight; more decompositions exist.
