Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461244, here are decompositions:

53 + 31461191 = 31461244
71 + 31461173 = 31461244
83 + 31461161 = 31461244
131 + 31461113 = 31461244
197 + 31461047 = 31461244
233 + 31461011 = 31461244
293 + 31460951 = 31461244
317 + 31460927 = 31461244

Showing the first eight; more decompositions exist.
