Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534544, here are decompositions:

43 + 31534501 = 31534544
61 + 31534483 = 31534544
103 + 31534441 = 31534544
211 + 31534333 = 31534544
313 + 31534231 = 31534544
487 + 31534057 = 31534544
577 + 31533967 = 31534544
673 + 31533871 = 31534544

Showing the first eight; more decompositions exist.
