Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619962, here are decompositions:

113 + 31619849 = 31619962
173 + 31619789 = 31619962
191 + 31619771 = 31619962
239 + 31619723 = 31619962
293 + 31619669 = 31619962
359 + 31619603 = 31619962
401 + 31619561 = 31619962
419 + 31619543 = 31619962

Showing the first eight; more decompositions exist.
