Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619704, here are decompositions:

101 + 31619603 = 31619704
173 + 31619531 = 31619704
317 + 31619387 = 31619704
443 + 31619261 = 31619704
491 + 31619213 = 31619704
521 + 31619183 = 31619704
587 + 31619117 = 31619704
761 + 31618943 = 31619704

Showing the first eight; more decompositions exist.
