Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487714, here are decompositions:

67 + 31487647 = 31487714
73 + 31487641 = 31487714
163 + 31487551 = 31487714
241 + 31487473 = 31487714
367 + 31487347 = 31487714
397 + 31487317 = 31487714
463 + 31487251 = 31487714
571 + 31487143 = 31487714

Showing the first eight; more decompositions exist.
