Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620046, here are decompositions:

53 + 31619993 = 31620046
197 + 31619849 = 31620046
239 + 31619807 = 31620046
257 + 31619789 = 31620046
443 + 31619603 = 31620046
503 + 31619543 = 31620046
587 + 31619459 = 31620046
659 + 31619387 = 31620046

Showing the first eight; more decompositions exist.
