Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570792, here are decompositions:

5 + 31570787 = 31570792
83 + 31570709 = 31570792
173 + 31570619 = 31570792
179 + 31570613 = 31570792
293 + 31570499 = 31570792
311 + 31570481 = 31570792
401 + 31570391 = 31570792
419 + 31570373 = 31570792

Showing the first eight; more decompositions exist.
