Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519452, here are decompositions:

11 + 31519441 = 31519452
71 + 31519381 = 31519452
73 + 31519379 = 31519452
89 + 31519363 = 31519452
131 + 31519321 = 31519452
163 + 31519289 = 31519452
199 + 31519253 = 31519452
241 + 31519211 = 31519452

Showing the first eight; more decompositions exist.
