Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478762, here are decompositions:

43 + 31478719 = 31478762
61 + 31478701 = 31478762
163 + 31478599 = 31478762
181 + 31478581 = 31478762
241 + 31478521 = 31478762
283 + 31478479 = 31478762
373 + 31478389 = 31478762
421 + 31478341 = 31478762

Showing the first eight; more decompositions exist.
