Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610002, here are decompositions:

29 + 31609973 = 31610002
71 + 31609931 = 31610002
131 + 31609871 = 31610002
233 + 31609769 = 31610002
311 + 31609691 = 31610002
419 + 31609583 = 31610002
461 + 31609541 = 31610002
503 + 31609499 = 31610002

Showing the first eight; more decompositions exist.
