Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610984, here are decompositions:

73 + 31610911 = 31610984
193 + 31610791 = 31610984
211 + 31610773 = 31610984
277 + 31610707 = 31610984
397 + 31610587 = 31610984
421 + 31610563 = 31610984
463 + 31610521 = 31610984
547 + 31610437 = 31610984

Showing the first eight; more decompositions exist.
