Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522678, here are decompositions:

137 + 31522541 = 31522678
149 + 31522529 = 31522678
227 + 31522451 = 31522678
347 + 31522331 = 31522678
401 + 31522277 = 31522678
431 + 31522247 = 31522678
449 + 31522229 = 31522678
587 + 31522091 = 31522678

Showing the first eight; more decompositions exist.
