Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508702, here are decompositions:

19 + 31508683 = 31508702
31 + 31508671 = 31508702
193 + 31508509 = 31508702
241 + 31508461 = 31508702
373 + 31508329 = 31508702
499 + 31508203 = 31508702
523 + 31508179 = 31508702
601 + 31508101 = 31508702

Showing the first eight; more decompositions exist.
