Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541006, here are decompositions:

67 + 31540939 = 31541006
139 + 31540867 = 31541006
193 + 31540813 = 31541006
223 + 31540783 = 31541006
283 + 31540723 = 31541006
307 + 31540699 = 31541006
313 + 31540693 = 31541006
337 + 31540669 = 31541006

Showing the first eight; more decompositions exist.
