Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539410, here are decompositions:

43 + 31539367 = 31539410
61 + 31539349 = 31539410
73 + 31539337 = 31539410
79 + 31539331 = 31539410
127 + 31539283 = 31539410
139 + 31539271 = 31539410
181 + 31539229 = 31539410
337 + 31539073 = 31539410

Showing the first eight; more decompositions exist.
