Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503444, here are decompositions:

83 + 31503361 = 31503444
101 + 31503343 = 31503444
103 + 31503341 = 31503444
107 + 31503337 = 31503444
113 + 31503331 = 31503444
131 + 31503313 = 31503444
227 + 31503217 = 31503444
241 + 31503203 = 31503444

Showing the first eight; more decompositions exist.
