Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540624, here are decompositions:

131 + 31540493 = 31540624
281 + 31540343 = 31540624
383 + 31540241 = 31540624
443 + 31540181 = 31540624
461 + 31540163 = 31540624
593 + 31540031 = 31540624
617 + 31540007 = 31540624
653 + 31539971 = 31540624

Showing the first eight; more decompositions exist.
