Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535070, here are decompositions:

11 + 31535059 = 31535070
13 + 31535057 = 31535070
37 + 31535033 = 31535070
59 + 31535011 = 31535070
71 + 31534999 = 31535070
89 + 31534981 = 31535070
109 + 31534961 = 31535070
157 + 31534913 = 31535070

Showing the first eight; more decompositions exist.
