Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541252, here are decompositions:

19 + 31541233 = 31541252
73 + 31541179 = 31541252
79 + 31541173 = 31541252
139 + 31541113 = 31541252
151 + 31541101 = 31541252
181 + 31541071 = 31541252
313 + 31540939 = 31541252
331 + 31540921 = 31541252

Showing the first eight; more decompositions exist.
