Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476554, here are decompositions:

3 + 31476551 = 31476554
7 + 31476547 = 31476554
37 + 31476517 = 31476554
97 + 31476457 = 31476554
103 + 31476451 = 31476554
163 + 31476391 = 31476554
181 + 31476373 = 31476554
211 + 31476343 = 31476554

Showing the first eight; more decompositions exist.
