Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505044, here are decompositions:

5 + 31505039 = 31505044
17 + 31505027 = 31505044
41 + 31505003 = 31505044
101 + 31504943 = 31505044
353 + 31504691 = 31505044
383 + 31504661 = 31505044
563 + 31504481 = 31505044
677 + 31504367 = 31505044

Showing the first eight; more decompositions exist.
