Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543804, here are decompositions:

41 + 31543763 = 31543804
53 + 31543751 = 31543804
107 + 31543697 = 31543804
113 + 31543691 = 31543804
233 + 31543571 = 31543804
353 + 31543451 = 31543804
443 + 31543361 = 31543804
503 + 31543301 = 31543804

Showing the first eight; more decompositions exist.
