Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615534, here are decompositions:

131 + 31615403 = 31615534
191 + 31615343 = 31615534
317 + 31615217 = 31615534
347 + 31615187 = 31615534
521 + 31615013 = 31615534
593 + 31614941 = 31615534
653 + 31614881 = 31615534
683 + 31614851 = 31615534

Showing the first eight; more decompositions exist.
