Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626734, here are decompositions:

43 + 31626691 = 31626734
67 + 31626667 = 31626734
127 + 31626607 = 31626734
163 + 31626571 = 31626734
241 + 31626493 = 31626734
313 + 31626421 = 31626734
367 + 31626367 = 31626734
397 + 31626337 = 31626734

Showing the first eight; more decompositions exist.
