Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490060, here are decompositions:

3 + 31490057 = 31490060
37 + 31490023 = 31490060
61 + 31489999 = 31490060
97 + 31489963 = 31490060
181 + 31489879 = 31490060
241 + 31489819 = 31490060
307 + 31489753 = 31490060
313 + 31489747 = 31490060

Showing the first eight; more decompositions exist.
