Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472764, here are decompositions:

41 + 31472723 = 31472764
101 + 31472663 = 31472764
131 + 31472633 = 31472764
173 + 31472591 = 31472764
227 + 31472537 = 31472764
263 + 31472501 = 31472764
503 + 31472261 = 31472764
563 + 31472201 = 31472764

Showing the first eight; more decompositions exist.
