Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543462, here are decompositions:

11 + 31543451 = 31543462
101 + 31543361 = 31543462
113 + 31543349 = 31543462
131 + 31543331 = 31543462
239 + 31543223 = 31543462
281 + 31543181 = 31543462
359 + 31543103 = 31543462
383 + 31543079 = 31543462

Showing the first eight; more decompositions exist.
