Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534226, here are decompositions:

43 + 31534183 = 31534226
109 + 31534117 = 31534226
193 + 31534033 = 31534226
277 + 31533949 = 31534226
307 + 31533919 = 31534226
379 + 31533847 = 31534226
397 + 31533829 = 31534226
457 + 31533769 = 31534226

Showing the first eight; more decompositions exist.
