Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461544, here are decompositions:

11 + 31461533 = 31461544
131 + 31461413 = 31461544
251 + 31461293 = 31461544
263 + 31461281 = 31461544
353 + 31461191 = 31461544
383 + 31461161 = 31461544
431 + 31461113 = 31461544
593 + 31460951 = 31461544

Showing the first eight; more decompositions exist.
