Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620892, here are decompositions:

53 + 31620839 = 31620892
71 + 31620821 = 31620892
113 + 31620779 = 31620892
293 + 31620599 = 31620892
311 + 31620581 = 31620892
419 + 31620473 = 31620892
449 + 31620443 = 31620892
461 + 31620431 = 31620892

Showing the first eight; more decompositions exist.
