Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575662, here are decompositions:

109 + 31575553 = 31575662
163 + 31575499 = 31575662
193 + 31575469 = 31575662
229 + 31575433 = 31575662
421 + 31575241 = 31575662
499 + 31575163 = 31575662
523 + 31575139 = 31575662
571 + 31575091 = 31575662

Showing the first eight; more decompositions exist.
