Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452662, here are decompositions:

13 + 31452649 = 31452662
79 + 31452583 = 31452662
181 + 31452481 = 31452662
211 + 31452451 = 31452662
379 + 31452283 = 31452662
421 + 31452241 = 31452662
463 + 31452199 = 31452662
541 + 31452121 = 31452662

Showing the first eight; more decompositions exist.
