Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465144, here are decompositions:

83 + 31465061 = 31465144
197 + 31464947 = 31465144
317 + 31464827 = 31465144
443 + 31464701 = 31465144
563 + 31464581 = 31465144
587 + 31464557 = 31465144
701 + 31464443 = 31465144
743 + 31464401 = 31465144

Showing the first eight; more decompositions exist.
