Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540554, here are decompositions:

53 + 31540501 = 31540554
61 + 31540493 = 31540554
83 + 31540471 = 31540554
113 + 31540441 = 31540554
137 + 31540417 = 31540554
191 + 31540363 = 31540554
211 + 31540343 = 31540554
257 + 31540297 = 31540554

Showing the first eight; more decompositions exist.
