Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541244, here are decompositions:

11 + 31541233 = 31541244
71 + 31541173 = 31541244
83 + 31541161 = 31541244
103 + 31541141 = 31541244
127 + 31541117 = 31541244
131 + 31541113 = 31541244
173 + 31541071 = 31541244
193 + 31541051 = 31541244

Showing the first eight; more decompositions exist.
