Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534538, here are decompositions:

37 + 31534501 = 31534538
97 + 31534441 = 31534538
109 + 31534429 = 31534538
127 + 31534411 = 31534538
241 + 31534297 = 31534538
307 + 31534231 = 31534538
397 + 31534141 = 31534538
421 + 31534117 = 31534538

Showing the first eight; more decompositions exist.
