Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542244, here are decompositions:

11 + 31542233 = 31542244
47 + 31542197 = 31542244
131 + 31542113 = 31542244
233 + 31542011 = 31542244
263 + 31541981 = 31542244
311 + 31541933 = 31542244
353 + 31541891 = 31542244
593 + 31541651 = 31542244

Showing the first eight; more decompositions exist.
