Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532070, here are decompositions:

7 + 31532063 = 31532070
67 + 31532003 = 31532070
103 + 31531967 = 31532070
139 + 31531931 = 31532070
149 + 31531921 = 31532070
257 + 31531813 = 31532070
421 + 31531649 = 31532070
431 + 31531639 = 31532070

Showing the first eight; more decompositions exist.
