Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610994, here are decompositions:

83 + 31610911 = 31610994
101 + 31610893 = 31610994
127 + 31610867 = 31610994
223 + 31610771 = 31610994
271 + 31610723 = 31610994
353 + 31610641 = 31610994
421 + 31610573 = 31610994
431 + 31610563 = 31610994

Showing the first eight; more decompositions exist.
