Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610342, here are decompositions:

3 + 31610339 = 31610342
73 + 31610269 = 31610342
199 + 31610143 = 31610342
229 + 31610113 = 31610342
331 + 31610011 = 31610342
349 + 31609993 = 31610342
409 + 31609933 = 31610342
523 + 31609819 = 31610342

Showing the first eight; more decompositions exist.
