Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537534, here are decompositions:

53 + 31537481 = 31537534
101 + 31537433 = 31537534
227 + 31537307 = 31537534
263 + 31537271 = 31537534
311 + 31537223 = 31537534
383 + 31537151 = 31537534
401 + 31537133 = 31537534
491 + 31537043 = 31537534

Showing the first eight; more decompositions exist.
