Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541264, here are decompositions:

31 + 31541233 = 31541264
103 + 31541161 = 31541264
151 + 31541113 = 31541264
163 + 31541101 = 31541264
193 + 31541071 = 31541264
397 + 31540867 = 31541264
541 + 31540723 = 31541264
571 + 31540693 = 31541264

Showing the first eight; more decompositions exist.
