Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497004, here are decompositions:

3 + 31497001 = 31497004
41 + 31496963 = 31497004
47 + 31496957 = 31497004
83 + 31496921 = 31497004
131 + 31496873 = 31497004
263 + 31496741 = 31497004
311 + 31496693 = 31497004
431 + 31496573 = 31497004

Showing the first eight; more decompositions exist.
