Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452804, here are decompositions:

11 + 31452793 = 31452804
41 + 31452763 = 31452804
73 + 31452731 = 31452804
83 + 31452721 = 31452804
127 + 31452677 = 31452804
137 + 31452667 = 31452804
181 + 31452623 = 31452804
197 + 31452607 = 31452804

Showing the first eight; more decompositions exist.
