Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610378, here are decompositions:

61 + 31610317 = 31610378
109 + 31610269 = 31610378
181 + 31610197 = 31610378
271 + 31610107 = 31610378
367 + 31610011 = 31610378
421 + 31609957 = 31610378
601 + 31609777 = 31610378
619 + 31609759 = 31610378

Showing the first eight; more decompositions exist.
