Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620094, here are decompositions:

101 + 31619993 = 31620094
113 + 31619981 = 31620094
251 + 31619843 = 31620094
293 + 31619801 = 31620094
353 + 31619741 = 31620094
491 + 31619603 = 31620094
563 + 31619531 = 31620094
593 + 31619501 = 31620094

Showing the first eight; more decompositions exist.
