Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554482, here are decompositions:

19 + 31554463 = 31554482
73 + 31554409 = 31554482
199 + 31554283 = 31554482
241 + 31554241 = 31554482
283 + 31554199 = 31554482
409 + 31554073 = 31554482
439 + 31554043 = 31554482
499 + 31553983 = 31554482

Showing the first eight; more decompositions exist.
