Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524642, here are decompositions:

73 + 31524569 = 31524642
101 + 31524541 = 31524642
109 + 31524533 = 31524642
173 + 31524469 = 31524642
223 + 31524419 = 31524642
239 + 31524403 = 31524642
311 + 31524331 = 31524642
349 + 31524293 = 31524642

Showing the first eight; more decompositions exist.
