Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619932, here are decompositions:

83 + 31619849 = 31619932
89 + 31619843 = 31619932
131 + 31619801 = 31619932
173 + 31619759 = 31619932
191 + 31619741 = 31619932
263 + 31619669 = 31619932
389 + 31619543 = 31619932
401 + 31619531 = 31619932

Showing the first eight; more decompositions exist.
