Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504554, here are decompositions:

7 + 31504547 = 31504554
61 + 31504493 = 31504554
73 + 31504481 = 31504554
101 + 31504453 = 31504554
167 + 31504387 = 31504554
181 + 31504373 = 31504554
197 + 31504357 = 31504554
227 + 31504327 = 31504554

Showing the first eight; more decompositions exist.
