Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524088, here are decompositions:

41 + 31524047 = 31524088
149 + 31523939 = 31524088
419 + 31523669 = 31524088
509 + 31523579 = 31524088
647 + 31523441 = 31524088
677 + 31523411 = 31524088
809 + 31523279 = 31524088
821 + 31523267 = 31524088

Showing the first eight; more decompositions exist.
