Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535192, here are decompositions:

19 + 31535173 = 31535192
61 + 31535131 = 31535192
79 + 31535113 = 31535192
109 + 31535083 = 31535192
181 + 31535011 = 31535192
193 + 31534999 = 31535192
211 + 31534981 = 31535192
313 + 31534879 = 31535192

Showing the first eight; more decompositions exist.
