Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525028, here are decompositions:

37 + 31524991 = 31525028
61 + 31524967 = 31525028
307 + 31524721 = 31525028
421 + 31524607 = 31525028
487 + 31524541 = 31525028
727 + 31524301 = 31525028
751 + 31524277 = 31525028
757 + 31524271 = 31525028

Showing the first eight; more decompositions exist.
