Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541276, here are decompositions:

7 + 31541269 = 31541276
43 + 31541233 = 31541276
97 + 31541179 = 31541276
103 + 31541173 = 31541276
163 + 31541113 = 31541276
229 + 31541047 = 31541276
337 + 31540939 = 31541276
409 + 31540867 = 31541276

Showing the first eight; more decompositions exist.
