Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503862, here are decompositions:

53 + 31503809 = 31503862
83 + 31503779 = 31503862
113 + 31503749 = 31503862
149 + 31503713 = 31503862
293 + 31503569 = 31503862
353 + 31503509 = 31503862
419 + 31503443 = 31503862
521 + 31503341 = 31503862

Showing the first eight; more decompositions exist.
