Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525070, here are decompositions:

43 + 31525027 = 31525070
79 + 31524991 = 31525070
103 + 31524967 = 31525070
277 + 31524793 = 31525070
307 + 31524763 = 31525070
349 + 31524721 = 31525070
397 + 31524673 = 31525070
463 + 31524607 = 31525070

Showing the first eight; more decompositions exist.
