Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461652, here are decompositions:

11 + 31461641 = 31461652
83 + 31461569 = 31461652
239 + 31461413 = 31461652
311 + 31461341 = 31461652
359 + 31461293 = 31461652
461 + 31461191 = 31461652
479 + 31461173 = 31461652
491 + 31461161 = 31461652

Showing the first eight; more decompositions exist.
