Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451692, here are decompositions:

113 + 31451579 = 31451692
131 + 31451561 = 31451692
431 + 31451261 = 31451692
491 + 31451201 = 31451692
521 + 31451171 = 31451692
659 + 31451033 = 31451692
743 + 31450949 = 31451692
863 + 31450829 = 31451692

Showing the first eight; more decompositions exist.
