Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466654, here are decompositions:

67 + 31466587 = 31466654
151 + 31466503 = 31466654
313 + 31466341 = 31466654
367 + 31466287 = 31466654
397 + 31466257 = 31466654
421 + 31466233 = 31466654
433 + 31466221 = 31466654
547 + 31466107 = 31466654

Showing the first eight; more decompositions exist.
