Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583070, here are decompositions:

19 + 31583051 = 31583070
23 + 31583047 = 31583070
37 + 31583033 = 31583070
47 + 31583023 = 31583070
89 + 31582981 = 31583070
109 + 31582961 = 31583070
139 + 31582931 = 31583070
157 + 31582913 = 31583070

Showing the first eight; more decompositions exist.
