Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542652, here are decompositions:

173 + 31542479 = 31542652
233 + 31542419 = 31542652
293 + 31542359 = 31542652
311 + 31542341 = 31542652
419 + 31542233 = 31542652
503 + 31542149 = 31542652
569 + 31542083 = 31542652
641 + 31542011 = 31542652

Showing the first eight; more decompositions exist.
