Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464590, here are decompositions:

13 + 31464577 = 31464590
19 + 31464571 = 31464590
43 + 31464547 = 31464590
97 + 31464493 = 31464590
109 + 31464481 = 31464590
127 + 31464463 = 31464590
139 + 31464451 = 31464590
151 + 31464439 = 31464590

Showing the first eight; more decompositions exist.
