Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524952, here are decompositions:

59 + 31524893 = 31524952
89 + 31524863 = 31524952
113 + 31524839 = 31524952
311 + 31524641 = 31524952
383 + 31524569 = 31524952
419 + 31524533 = 31524952
443 + 31524509 = 31524952
659 + 31524293 = 31524952

Showing the first eight; more decompositions exist.
