Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619674, here are decompositions:

5 + 31619669 = 31619674
71 + 31619603 = 31619674
113 + 31619561 = 31619674
131 + 31619543 = 31619674
173 + 31619501 = 31619674
347 + 31619327 = 31619674
461 + 31619213 = 31619674
467 + 31619207 = 31619674

Showing the first eight; more decompositions exist.
