Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576304, here are decompositions:

37 + 31576267 = 31576304
43 + 31576261 = 31576304
73 + 31576231 = 31576304
103 + 31576201 = 31576304
313 + 31575991 = 31576304
367 + 31575937 = 31576304
577 + 31575727 = 31576304
607 + 31575697 = 31576304

Showing the first eight; more decompositions exist.
