Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610684, here are decompositions:

43 + 31610641 = 31610684
97 + 31610587 = 31610684
103 + 31610581 = 31610684
163 + 31610521 = 31610684
181 + 31610503 = 31610684
271 + 31610413 = 31610684
331 + 31610353 = 31610684
367 + 31610317 = 31610684

Showing the first eight; more decompositions exist.
