Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534028, here are decompositions:

61 + 31533967 = 31534028
79 + 31533949 = 31534028
109 + 31533919 = 31534028
157 + 31533871 = 31534028
181 + 31533847 = 31534028
199 + 31533829 = 31534028
307 + 31533721 = 31534028
367 + 31533661 = 31534028

Showing the first eight; more decompositions exist.
