Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456604, here are decompositions:

7 + 31456597 = 31456604
73 + 31456531 = 31456604
103 + 31456501 = 31456604
163 + 31456441 = 31456604
313 + 31456291 = 31456604
367 + 31456237 = 31456604
601 + 31456003 = 31456604
643 + 31455961 = 31456604

Showing the first eight; more decompositions exist.
