Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506554, here are decompositions:

31 + 31506523 = 31506554
43 + 31506511 = 31506554
181 + 31506373 = 31506554
223 + 31506331 = 31506554
271 + 31506283 = 31506554
283 + 31506271 = 31506554
307 + 31506247 = 31506554
463 + 31506091 = 31506554

Showing the first eight; more decompositions exist.
