Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523060, here are decompositions:

7 + 31523053 = 31523060
73 + 31522987 = 31523060
109 + 31522951 = 31523060
313 + 31522747 = 31523060
367 + 31522693 = 31523060
397 + 31522663 = 31523060
463 + 31522597 = 31523060
601 + 31522459 = 31523060

Showing the first eight; more decompositions exist.
