Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534466, here are decompositions:

37 + 31534429 = 31534466
43 + 31534423 = 31534466
97 + 31534369 = 31534466
283 + 31534183 = 31534466
349 + 31534117 = 31534466
409 + 31534057 = 31534466
433 + 31534033 = 31534466
487 + 31533979 = 31534466

Showing the first eight; more decompositions exist.
