Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519592, here are decompositions:

61 + 31519531 = 31519592
73 + 31519519 = 31519592
109 + 31519483 = 31519592
151 + 31519441 = 31519592
211 + 31519381 = 31519592
229 + 31519363 = 31519592
271 + 31519321 = 31519592
523 + 31519069 = 31519592

Showing the first eight; more decompositions exist.
