Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610694, here are decompositions:

53 + 31610641 = 31610694
107 + 31610587 = 31610694
113 + 31610581 = 31610694
131 + 31610563 = 31610694
173 + 31610521 = 31610694
191 + 31610503 = 31610694
257 + 31610437 = 31610694
281 + 31610413 = 31610694

Showing the first eight; more decompositions exist.
