Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462628, here are decompositions:

19 + 31462609 = 31462628
37 + 31462591 = 31462628
97 + 31462531 = 31462628
157 + 31462471 = 31462628
271 + 31462357 = 31462628
277 + 31462351 = 31462628
487 + 31462141 = 31462628
607 + 31462021 = 31462628

Showing the first eight; more decompositions exist.
