Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455592, here are decompositions:

59 + 31455533 = 31455592
71 + 31455521 = 31455592
89 + 31455503 = 31455592
173 + 31455419 = 31455592
293 + 31455299 = 31455592
353 + 31455239 = 31455592
383 + 31455209 = 31455592
431 + 31455161 = 31455592

Showing the first eight; more decompositions exist.
